For researchers and pharmaceutical manufacturers, the precise specifications of a chemical compound are critical for successful application and regulatory compliance. Sodium Salicylate (CAS 54-21-7) is no different. When you decide to buy Sodium Salicylate, a thorough understanding of its key specifications will ensure you procure a product that meets your exact needs. This guide focuses on the essential parameters that procurement and R&D professionals should consider.
Understanding Purity and Grade
The most crucial specification for Sodium Salicylate is its purity, often defined by its assay. High-quality Sodium Salicylate for pharmaceutical use typically boasts an assay of 99.0% to 101.0%. This high purity ensures minimal impurities, which is vital for consistent therapeutic effects and to prevent adverse reactions in drug formulations. Furthermore, the grade of the product is important; USP (United States Pharmacopeia) and BP (British Pharmacopoeia) grades are the industry standards for pharmaceutical applications, indicating adherence to rigorous quality and safety protocols.
Physical and Chemical Properties
Beyond purity, the physical form and other chemical properties are key. Sodium Salicylate is commonly supplied as colorless small crystals, shiny flakes, or a white crystalline powder. This physical appearance is a visual indicator of quality. Other critical specifications detailed in Technical Data Sheets (TDS) include limits for heavy metals (≤20ppm), chloride (≤200ppm), sulphate (≤600ppm), and loss on drying (≤0.5%). These parameters ensure the product's stability and suitability for various chemical processes and formulations. Manufacturers also provide Safety Data Sheets (SDS) which detail safe handling, storage, and emergency procedures.
Sourcing and Inquiry Best Practices
When you are ready to purchase Sodium Salicylate, it's essential to inquire about these specifications directly from the supplier. Requesting a detailed Certificate of Analysis (CoA) along with the MSDS and TDS is standard practice. For businesses looking for a reliable Sodium Salicylate supplier, partnering with manufacturers who transparently provide this information, especially those in China with large production capacities (e.g., 5000 tons per year), ensures a dependable source. Always compare the specifications and Sodium Salicylate price from different suppliers to make an informed decision for your procurement needs.
