For any B2B buyer, a thorough understanding of a chemical's properties and purity is fundamental to ensuring successful application and a good return on investment. Trisodium Phosphate Anhydrous (CAS 7632-05-5) is a chemical compound that requires careful consideration of its characteristics. This article, brought to you by a leading manufacturer and supplier, aims to clarify these crucial aspects for procurement professionals and R&D scientists.

The primary defining characteristic of Trisodium Phosphate Anhydrous is its chemical composition: Na₃PO₄. It typically appears as a white crystalline powder or granules. A key physical property to note is its slight hygroscopicity, meaning it can absorb moisture from the air. This necessitates proper storage in sealed containers in dry conditions to maintain its anhydrous state and prevent caking. Its solubility in water is significant, making it easy to incorporate into aqueous formulations. However, it is notably insoluble in ethanol, a detail that can be important for certain solvent-based applications.

When you purchase Trisodium Phosphate Anhydrous, the 'purity' or 'assay' is a critical specification. The provided material details indicate an assay percentage of ≥97%. This figure represents the minimum content of the active compound, Trisodium Phosphate. Other important purity indicators include the level of water-insoluble substances, which should be very low (≤0.10%), and the pH value of a solution, typically ranging between 11.5 to 12.5 for a 1% solution. These parameters are vital for applications where precise chemical reactions or formulations are required, such as in food processing or as a laboratory reagent.

The CAS number, 7632-05-5, serves as a universal identifier for this specific chemical. When sourcing, always verify that the CAS number matches your requirements. We, as a dedicated Trisodium Phosphate Anhydrous supplier in China, ensure that all our product documentation, including Certificates of Analysis, clearly states these critical purity parameters. This transparency allows buyers to confidently assess if the product aligns with their needs, whether for buffering, emulsification, or other specialized uses.

Understanding the implications of these properties is crucial for successful procurement. For instance, its high pH makes it an effective alkaline agent, useful in pH adjustment and cleaning formulations. Its ability to form stable chelates with metal ions contributes to its effectiveness as a water softener and stabilizer. For R&D scientists and formulators, knowing these properties allows for more precise application development. For purchasing managers, confirming purity ensures that the product performs as expected, minimizing batch-to-batch variability and ensuring customer satisfaction. When you are looking to buy Trisodium Phosphate Anhydrous, engaging with a reputable manufacturer that provides detailed specifications and reliable CoAs is the most prudent approach.
