For professionals in chemical research, development, and formulation, a deep understanding of product specifications is not just beneficial, it's critical for success. Sodium p-toluene sulfonate, specifically the 78% purity grade with CAS number 657-84-1, is a chemical intermediate that demands attention to detail regarding its properties. This article aims to provide R&D scientists and product formulators with the essential information needed to confidently procure and utilize this versatile compound.

The core value proposition of Sodium p-toluene sulfonate lies in its precise chemical and physical characteristics. As a manufacturer and supplier, we ensure that our product meets stringent quality controls. The typical appearance is a white powder, indicative of its refined state. Crucially, the purity of the compound is specified as ≥78.0%. This level of purity is vital for applications such as the amendment of material pulp in the chemical industry, where consistency is key to achieving desired outcomes in processing. Similarly, in synthetic detergent formulations, precise purity ensures optimal performance and stability.

Beyond purity, other key specifications that B2B buyers should scrutinize include moisture content, typically targeted at ≤6.0%, and inorganic substance levels, often kept at ≤14.0%. These parameters directly influence the chemical's reactivity, shelf life, and compatibility with other ingredients. The pH range, usually between 7 and 12 as measured by a pH instrument, is also a critical indicator for formulators, particularly when integrating the chemical into aqueous systems or specific reaction chemistries. Understanding these technical details empowers scientists to make informed decisions when sourcing this chemical.

When you choose to buy Sodium p-toluene sulfonate, selecting a supplier that provides detailed Certificates of Analysis (CoA) for each batch is highly recommended. This documentation verifies that the product consistently meets the stated specifications. For R&D purposes, having access to reliable data on CAS 657-84-1 ensures reproducibility in experiments and product development. Manufacturers committed to quality will readily provide such documentation, alongside robust safety data sheets (SDS) to guide safe handling and storage.

In conclusion, for effective procurement and application of Sodium p-toluene sulfonate, particularly the 78% grade, a thorough understanding of its technical specifications is indispensable. We, as a dedicated chemical supplier, are committed to providing products that meet these rigorous standards.
