The foundation of any successful procurement strategy lies in a precise understanding of the product's technical specifications. For ethyl benzenesulphonate, the visual appearance is a primary indicator of quality. Buyers should specifically target materials described as colorless or transparent, as these attributes often correlate with high purity and the absence of oxidation byproducts. In the current market, observed listings frequently describe the substance as a colorless liquid or oily liquid, with specific refractive indices and densities serving as key verification points.

When evaluating technical data, buyers must look for consistency in physical constants. Standard literature values for similar esters and sulphonates often cite a boiling point in the range of 76.5 to 77.5 °C and a melting point near -84 °C. Density is another critical parameter, typically observed around 0.90 g/cm³ at 20 °C. However, it is vital to note that observed market data for related compounds sometimes lists density as 0.902 g/mL at 25 °C. Procurement teams must verify which temperature standard the supplier uses, as discrepancies can lead to calculation errors in inventory management and dosing.

The molecular weight of the compound is another fixed attribute that aids in identification. A molecular weight of approximately 88.11 is a common reference point for related esters, though specific sulphonate derivatives may vary. Buyers should request a Certificate of Analysis (CoA) that explicitly lists the refractive index, flash point, and vapor pressure. For instance, a flash point of 26 °F and a vapor density of 3 (relative to air at 20 °C) are specific data points that help confirm the identity of the chemical. Ensuring the product matches these physical constants is the first line of defense against counterfeit or degraded stock.

Compliance, Certification, and Grade Standards

In the industrial sector, the distinction between grades is paramount. The market for ethyl benzenesulphonate is dominated by Industrial Grade products, which must adhere to strict purity thresholds. Observed standards in the sector often specify a minimum purity of 99% or 99.5%. When sourcing, buyers must verify that the supplier explicitly states the grade standard as "Industrial Grade" and provides a purity guarantee that meets or exceeds the 99.5% minimum threshold.

Certification and compliance extend beyond purity to include safety and environmental standards. While specific certification bodies are not universally mandated for all industrial chemicals, buyers should verify that the supplier adheres to recognized quality management systems. The origin of the product is a significant compliance factor. Data indicates that a substantial portion of this chemical is sourced from China, with specific regions like Hebei being noted as production hubs. Buyers should confirm the country of origin and ensure that the supply chain complies with international trade regulations and import requirements for the destination country.

Furthermore, the chemical's classification as an organic acid derivative or its specific application in surfactant production may trigger specific regulatory requirements. Buyers must ensure that the supplier can provide documentation regarding the absence of prohibited impurities, such as N-butyl alcohol, which in some related specifications is limited to a maximum of 0.2%. This level of detail is crucial for maintaining product integrity in sensitive applications.

Cost Drivers and Pricing Dynamics

The pricing of industrial ethyl benzenesulphonate is influenced by a complex interplay of raw material costs, packaging requirements, and order volume. The observed price range in the market is extensive, spanning from $0.50 to $1900.00 per unit. This wide variance is often a result of differences in packaging formats, purity levels, and the scale of the transaction. A unit price of $0.50 might reflect a bulk industrial drum purchase, whereas a price near $1900 could indicate a specialized, small-batch, or high-purity laboratory grade product.

Packaging is a significant cost driver. The market offers diverse packaging options including barrels, drums, IBCs (Intermediate Bulk Containers), and bottles. Standard specifications often list 180 kg drums or 200 kg barrels as common units. Some suppliers offer IBCs with capacities of 1000 kg, which can reduce the per-unit cost for large-volume buyers. The choice between a 180 kg drum and an IBC can significantly impact the total landed cost, including logistics and handling fees.

Minimum Order Quantities (MOQ) also play a critical role in cost determination. Observed MOQs range from 1 unit to 1000 units, with some specific listings indicating an MOQ of 14.4 metric tons for large-scale industrial contracts. Buyers must align their procurement volume with the supplier's MOQ to avoid unnecessary premiums. Additionally, the availability of customization services can influence pricing. Suppliers offering tailored packaging or specific purity adjustments may charge a premium, but this can be cost-effective for buyers with unique operational needs.

Typical Applications and Usage Scenarios

Ethyl benzenesulphonate finds its primary utility in the industrial sector, particularly in applications requiring high-purity solvents or surfactant intermediates. The "Industrial Grade" designation suggests its use in large-scale manufacturing processes rather than consumer-facing products. One of the key application areas is in the production of detergents and cleaning agents, where the chemical acts as a surfactant or emulsifier. Its colorless nature and specific solvency properties make it ideal for formulations where visual clarity is required.

The chemical's physical properties, such as its oily liquid appearance and specific boiling point, make it suitable for various chemical synthesis processes. It is often used as a solvent in the extraction of organic compounds or as a reaction medium in the production of other esters and sulphonates. The stability of the product, indicated by a shelf life of up to 24 months for related ethoxylated alcohols, suggests it is suitable for storage and distribution in industrial supply chains.

Buyers should also consider the chemical's compatibility with other industrial materials. The flash point of 26 °F indicates that the substance is flammable and requires careful handling and storage. This characteristic influences its application in high-temperature processes, where safety protocols must be strictly enforced. Understanding these application nuances helps buyers select the right grade and packaging for their specific manufacturing needs.
