Source Cyclohexanone for Solvents, Synthesis, and Coatings

Cyclohexanone Sourcing Guide

Procurement professionals must first distinguish between the specific chemical entity of cyclohexanone and its closely related isomers or precursors like cyclohexane. The supplied data indicates that while some listings explicitly name cyclohexanone, others may list cyclohexane or generic models like CYC, requiring careful verification of the molecular identity before ordering. Buyers should scrutinize the "Other Names" field to ensure the product matches the intended synthesis requirements, as confusion between these compounds can lead to significant process failures in downstream manufacturing.

The observed market signals reveal a wide variance in packaging and model specifications, ranging from 150kg drums to 190kg containers and ISO tanks. This diversity suggests that suppliers offer flexible logistics solutions, yet the inconsistency in model naming conventions necessitates a rigorous cross-check of the product model against the chemical formula. Procurement teams must confirm whether the listed model corresponds to the specific purity grade required, as the data shows variations from 99.0% to 99.9% purity, which directly impacts the suitability for high-precision organic synthesis applications.

Product Scope and Observed Listing Signals

Buyers should analyze the physical state and appearance data to confirm the product meets operational handling requirements. The provided facts consistently describe the substance as a transparent, colorless liquid with a specific flash point of 44ºC and a boiling point of 155.75°C. These physical properties are critical for storage planning and safety protocols, ensuring that the liquid can be managed within standard industrial temperature ranges without unexpected volatility or freezing issues during transport.

The scope of available products includes various packaging formats such as metal drums, iron drums, and ISO tanks, with minimum order quantities starting as low as one kilogram. This flexibility allows small-scale research projects to access the material without excessive inventory costs, while larger industrial buyers can utilize bulk tank options for efficiency. However, the presence of different packaging standards, such as 150kg versus 190kg drums, requires buyers to align their internal logistics capabilities with the specific supplier's offering to avoid handling complications.

Technical Specifications to Verify

Verification of purity levels is the primary technical hurdle for buyers, as the data presents a range from 99.0% to 99.9% minimum purity. Procurement teams must explicitly request batch-specific certificates of analysis to confirm the exact purity percentage, as the difference between 99.0% and 99.9% can significantly affect reaction yields in organic synthesis. Relying on general listing descriptions without specific batch data introduces a risk of receiving material that fails to meet the stringent requirements of high-value chemical manufacturing processes.

Chemical composition details regarding water content, acidity, and hazen color must be validated against the specific constraints of the buyer's production line. The observed specifications indicate a maximum water content of 0.1% and acidity as acrylic acid of 0.01%, alongside a hazen color limit of 15. These impurities can catalyze unwanted side reactions or degrade product quality, so buyers must ensure that the supplier's standard industrial grade aligns with the tolerance limits of their specific application before finalizing any purchase agreement.

Compliance and Safety Documentation

Safety data sheets must be reviewed to confirm the hazard classification and UN number associated with the specific shipment. The provided facts list a UN number of 1915 and a hazard class of 3.3, which are essential for determining the correct shipping regulations and storage requirements. Buyers must ensure that the documentation provided by the supplier matches these identifiers exactly, as discrepancies can lead to customs delays or regulatory violations during international transport from the origin location.

The flash point of 44ºC classifies the material as a flammable liquid, necessitating strict adherence to fire safety protocols during storage and handling. Procurement teams should verify that the supplier's packaging and labeling comply with the specific hazard class requirements for Class 3.3 flammable liquids. Additionally, the origin location in China or Shandong implies specific export compliance standards that must be met, requiring buyers to confirm that all necessary safety documentation accompanies the shipment to ensure legal entry into the destination country.

Cost Drivers and Commercial Terms

The observed price range of 0.25 to 3000 USD reflects significant variability based on purity, packaging, and order volume. Buyers must understand that the lower end of this range likely corresponds to smaller quantities or lower purity grades, while the higher end may reflect bulk industrial orders or specialized packaging like ISO tanks. It is crucial to negotiate based on the specific technical requirements rather than the broad listing range, as the cost per kilogram can fluctuate dramatically depending on the agreed-upon purity and delivery terms.

Lead times and delivery windows are critical commercial factors, with the data indicating a delivery window of within 7-15 days. This timeframe suggests a relatively agile supply chain, yet buyers should confirm if this lead time applies to sample orders or bulk shipments, as the latter may require longer production cycles. The availability of samples is noted as a positive factor for quality verification, but procurement teams must clarify whether sample costs are deducted from the final bulk order to accurately calculate the total cost of ownership.

Supplier Qualification and Quality Control

Supplier qualification should focus on the consistency of their industrial grade standards and the reliability of their quality control processes. The data mentions "Industrial" and "Industrial Grade" standards, but buyers must verify if these align with international quality benchmarks or if they are internal company standards. It is advisable to request a detailed quality management system overview to ensure that the supplier maintains consistent purity levels and impurity controls across different production batches.

Quality control verification should include a review of the supplier's testing protocols for key parameters like water content and acidity. Since the specifications list maximum limits for these impurities, buyers must ensure that the supplier performs regular testing and provides transparent results. The presence of customization options suggests flexibility, but this should not come at the expense of rigorous quality assurance, as the buyer must be confident that any customized specifications will still meet the core safety and performance requirements of their application.

Long-Term Procurement Checks

Establishing a long-term relationship requires regular audits of the supplier's ability to maintain consistent product specifications over time. Buyers should implement a schedule for periodic re-testing of incoming batches to verify that the purity, color, and impurity levels remain within the agreed-upon limits. This proactive approach helps identify any drift in quality before it impacts production, ensuring that the supply chain remains stable and reliable for continuous manufacturing operations.

Supply chain resilience should be assessed by monitoring the supplier's ability to meet demand during peak periods and their capacity to handle logistics disruptions. The observed origin in Shandong and the variety of packaging options provide some flexibility, but buyers must evaluate the supplier's contingency plans for raw material shortages or transport delays. Regular communication regarding production schedules and inventory levels will help mitigate risks and ensure a steady flow of cyclohexanone to support ongoing organic synthesis and solvent applications.
