When working with chemical compounds, understanding their specifications and purity levels is paramount, especially for applications in sensitive industries like pharmaceuticals, food, and cosmetics. EDTA Disodium Salt Dihydrate is no exception, and its efficacy and safety are directly linked to its quality. This article explores the essential aspects of its purity, specifications, and the importance of sourcing it from reliable providers.

EDTA Disodium Salt Dihydrate is commonly available in various grades, with USP (United States Pharmacopeia) grade being one of the most recognized and sought-after for pharmaceutical and medical applications. USP grade ensures that the chemical meets rigorous standards for purity, identity, strength, and quality. For instance, a typical specification for USP grade might require a minimum assay of 99-99.5%. Other critical parameters checked include limits for impurities such as chlorides, sulfates, and heavy metals like iron and lead, ensuring that the product is safe for human consumption or application. The presence of the dihydrate form, indicated by the formula C10H14N2Na2O8·2H2O, is also a key specification.

Beyond USP grade, there are also Food Grade and Industrial Grade versions of EDTA disodium salt. Food Grade ensures it meets the safety requirements for use in food and beverages as a preservative or stabilizer. Industrial Grade is typically used in applications where the highest purity is not as critical, such as in some water treatment or cleaning processes. Understanding the intended application is key to selecting the correct grade and ensuring optimal performance and compliance.

For businesses that require EDTA disodium salt, the choice of supplier is critical. Working with reputable EDTA disodium salt suppliers ensures that you receive products that consistently meet the specified quality standards. This is particularly important when looking to buy EDTA disodium salt Dihydrate for sensitive applications where product failure due to impure ingredients could have severe consequences. A trustworthy supplier will often provide detailed specification sheets and certificates of analysis (CoA) for their products.

The CAS number 6381-92-6 uniquely identifies this specific form of EDTA. Knowing the correct CAS number is essential for accurate identification and regulatory compliance when ordering or handling the chemical. Whether you need it for precise laboratory experiments, formulation in personal care products, or as a key pharmaceutical intermediate, obtaining high-quality EDTA Disodium Salt Dihydrate from a dependable source is fundamental to achieving successful outcomes.
