For professionals in the chemical and pharmaceutical industries, selecting the right specifications for raw materials like Sodium 4-Hydroxybenzenesulfonate Dihydrate (CAS 10580-19-5) is critical to the success of their projects. When aiming to purchase this organic intermediate, understanding the key specifications ensures you obtain a product that meets your exact requirements and contributes to predictable outcomes in your synthesis or formulation processes.

The most crucial specification for Sodium 4-Hydroxybenzenesulfonate Dihydrate is its purity. High-purity grades, typically 97% or higher, are often preferred for sensitive applications where impurities could interfere with reactions or compromise the final product. When sourcing from manufacturers, always request a Certificate of Analysis (CoA) that clearly states the purity level and the analytical methods used. This is a standard practice for reliable chemical suppliers, especially those in China.

Another important specification is the physical appearance. Sodium 4-Hydroxybenzenesulfonate Dihydrate is commonly described as a pale yellow to beige, gold, or even green powder. While slight variations in color can occur due to trace impurities, a consistent and well-defined appearance indicates good manufacturing practices. When you buy this product, ensure the supplier provides a clear description of its expected appearance.

Other specifications that may be relevant depending on your application include moisture content, melting point (which is typically very high, often above 300°C for this compound), and the presence of specific metallic impurities. Always consult the Technical Data Sheet (TDS) provided by the manufacturer for a comprehensive list of specifications. By paying close attention to these details, procurement managers and R&D scientists can confidently purchase Sodium 4-Hydroxybenzenesulfonate Dihydrate from reputable suppliers, ensuring the quality and efficacy of their chemical operations.
