Based on available market data, this substance is frequently categorized under synthesis material intermediates, specifically identified by the CAS Registry Number 90-98-2. Buyers must recognize that while the core chemical identity is consistent, the physical presentation can vary significantly between suppliers. Observed product attributes indicate that the material may appear as a crystal or a powder, with color ranging from white to light yellow. This variability necessitates that procurement teams do not assume a single form factor but rather specify the required appearance in their purchase orders.

The technical profile of this intermediate is defined by specific physicochemical constants. The molecular formula is recorded as C13H8Cl2O, with a corresponding molecular weight of 251.11. For applications requiring precise stoichiometry or reaction kinetics, these figures are non-negotiable. The melting point is a critical thermal property, observed in the range of 144-147 °C, which serves as a primary indicator of purity and phase transition behavior. Furthermore, the boiling point is documented at 353 °C, a figure that is also cited as a literature value (Lit.) in various technical sheets. Density is another essential parameter for logistics and storage calculations, with observed values around 1.45 g/cm³.

It is imperative for buyers to distinguish between different product models and grades that may share the same CAS number but differ in application suitability. The market data reveals multiple product models associated with this chemical, including 90-98-2, 362, ZXY0914, MXY12254, LMR0515, WXY0208, MXY12208, FYQ12151, and CAS 85-29-0. While 90-98-2 is the primary identifier for the target substance, the presence of other model numbers suggests that suppliers may offer variations or related compounds under similar naming conventions. Buyers must verify that the specific model number on the certificate of analysis matches the intended chemical structure to avoid receiving a different isomer or derivative.

Compliance Framework and Certification Verification

In the chemical intermediates sector, compliance is not merely a regulatory formality but a prerequisite for operational continuity. The supply chain for industrial white p-dichlorobenzophenone is subject to rigorous quality and environmental standards. Trusted suppliers in this domain typically hold a portfolio of certifications that validate their manufacturing processes. Common certifications observed in the market include ISO, RoHS, CIQ, CCIC, and ISO9001. These certifications indicate adherence to international quality management systems, restrictions on hazardous substances, and inspection protocols required for export and domestic trade.

The grade standard of the product is a critical compliance metric. The market data indicates that this material is often classified as "Electron Grade" or "Industrial Grade." This distinction is vital because Electron Grade materials typically require higher purity levels and stricter impurity controls compared to general Industrial Grade products. Buyers must explicitly request the Grade Standard specification on the product datasheet. Additionally, the purity standard is frequently cited as 99% or a range of 98-99%. It is crucial to note that while 99% is a common benchmark, the actual purity must be verified against the specific batch certificate. Relying on a general "99%" claim without a batch-specific analysis report can lead to quality discrepancies in downstream manufacturing processes.

Environmental protection is another significant compliance factor. The product attributes confirm that environmental protection measures are often integrated into the supply chain, with some listings explicitly stating "Environmental Protection: Yes." This suggests that the production and handling of the material adhere to specific environmental regulations, which is increasingly important for companies with sustainability mandates. Furthermore, the origin of the product is predominantly China, with specific mentions of Jiangsu as a production hub. Buyers sourcing from this region should ensure that the supplier's export documentation aligns with the origin claims to facilitate smooth customs clearance.

Cost Drivers and Pricing Dynamics

The pricing structure for industrial white p-dichlorobenzophenone is influenced by a complex interplay of factors, including raw material costs, packaging requirements, and order volume. The observed price range in the market is extensive, spanning from $0.20 to $1,100.00 per unit. This wide variance is not indicative of a single product but rather reflects differences in purity, packaging size, minimum order quantities (MOQ), and the specific supplier's pricing strategy. A price at the lower end of the spectrum likely corresponds to bulk industrial-grade material with standard packaging, while prices at the higher end may reflect electron-grade purity, specialized packaging, or smaller batch sizes.

The Minimum Order Quantity (MOQ) is a primary driver of unit cost. The market data shows an MOQ range from 1 kg to 2,000 units. Suppliers offering an MOQ of 1 kg often charge a premium per kilogram to cover handling and administrative costs associated with small shipments. Conversely, buyers purchasing in bulk, such as 200 kg drums or 1,000 kg IBC drums, can typically negotiate lower unit prices. The packaging format also impacts cost. Options include 25 kg fiber drums, 25L barrels, 200 kg drums, and 1,000 kg IBC drums. The choice of packaging should balance cost efficiency with logistical capabilities and storage constraints.

Lead times and delivery terms also play a role in the total cost of ownership. Some suppliers offer a delivery time of 3-5 days, which may command a higher price due to expedited logistics. Buyers must weigh the cost of expedited shipping against the potential production delays caused by waiting for standard lead times. Additionally, the availability of free samples can be a cost-saving measure during the qualification phase, allowing buyers to verify product quality before committing to a large purchase. However, buyers should be aware that while samples may be free, shipping costs are often the responsibility of the purchaser.

Typical Applications and Functional Usage

The industrial white p-dichlorobenzophenone is primarily utilized within the chemical industry as a synthesis material intermediate. Its specific chemical structure makes it suitable for various downstream applications, though the exact end-use depends on the purity and grade of the material. The product attributes list "Chemical Industry" as a primary usage category, indicating its role as a building block for more complex chemical compounds. In some contexts, the material is associated with functions related to rehabilitation, although this term requires careful interpretation in a chemical context, potentially referring to the restoration of material properties or specific industrial processes.

The classification of the material as an "Aromatic Hydrocarbon" and an "Unsaturated Acid" (in some listings) suggests its reactivity in organic synthesis reactions. These properties are essential for manufacturers producing pharmaceuticals, agrochemicals, or advanced materials. The "Rehabilitation" function mentioned in the data may imply a role in processes where the material aids in the recovery or treatment of other substances, though this is less common for standard intermediates and should be verified against specific technical datasheets.

Buyers should also consider the physical form when selecting the product for their applications. The material is available in forms ranging from powder to crystal. Powder forms are often preferred for mixing and blending processes, while crystal forms may be more suitable for reactions requiring precise melting points or controlled dissolution rates. The color variation from white to light yellow can also be an indicator of the material's condition and suitability for specific aesthetic or functional requirements in the final product.

Supplier Evaluation and Quality Control Protocols

Evaluating suppliers for industrial white p-dichlorobenzophenone requires a multi-faceted approach that goes beyond price comparison. The first step is to verify the supplier's certification status. A reputable supplier should provide valid documentation for ISO, RoHS, CIQ, CCIC, and ISO9001 certifications. These documents should be current and issued by recognized bodies. Buyers should also check the supplier's origin, ensuring that the claimed location, such as Jiangsu, China, matches the shipping documentation and manufacturing facilities.

Quality control is paramount in the chemical supply chain. Buyers must insist on a Certificate of Analysis (CoA) for every batch purchased. The CoA should confirm the molecular formula (C13H8Cl2O), molecular weight (251.11), melting point (144-147 °C), boiling point (353 °C), and density (1.45 g/cm³). It should also verify the purity level, whether it is 99% or within the 98-99% range, and confirm the grade standard (Electron Grade or Industrial Grade). The absence of a detailed CoA is a red flag that should not be ignored.

Customization availability is another factor to consider. Some suppliers offer customization services, which can be beneficial for buyers with specific packaging or purity requirements. The ability to customize packaging, such as choosing between 25 kg drums, 200 kg drums, or IBC drums, allows buyers to optimize their logistics and storage. Additionally, the availability of free samples enables buyers to conduct their own internal quality tests before finalizing a long-term contract.

Long-Term Procurement Considerations and Risk Management

Establishing a long-term procurement strategy for industrial white p-dichlorobenzophenone involves more than securing a single transaction. Buyers must consider the stability of the supply chain, the consistency of product quality, and the scalability of the supplier's operations. The wide range of product models and packaging options indicates a dynamic market, but it also introduces the risk of confusion or misidentification. To mitigate this, buyers should establish a clear specification sheet that includes the CAS number, molecular formula, physical form, and required purity level. This document should be referenced in all purchase orders and communication with suppliers.

Risk management also extends to the verification of standards and specifications. While the market data provides a range of observed values, buyers should not assume that every listed product satisfies all attributes. For instance, while some products are listed with a "Rehabilitation" function, others may not have this attribute. Buyers must verify that the specific product they are purchasing meets all their operational requirements. Similarly, the "Environmental Protection" attribute should be confirmed for each batch to ensure compliance with the buyer's sustainability goals.

Finally, buyers should monitor the market for changes in lead times, MOQs, and pricing. The observed lead time of 3-5 days and MOQ range of 1-2,000 units suggest a flexible market, but external factors such as raw material shortages or regulatory changes can impact these figures. Maintaining a relationship with multiple suppliers can provide a buffer against supply disruptions. By focusing on technical specifications, compliance, and quality control, buyers can ensure a reliable and efficient supply of industrial white p-dichlorobenzophenone for their manufacturing needs.
