Ethylenediaminetetraacetic acid, trisodiumsalt hydrate

Description:
Ethylenediaminetetraacetic acid, trisodium salt hydrate, commonly referred to as EDTA trisodium salt, is a chelating agent widely used in various applications, including pharmaceuticals, food preservation, and analytical chemistry. It is a white, crystalline powder that is highly soluble in water, forming a clear solution. The compound acts by binding to metal ions, effectively sequestering them and preventing their reactivity, which is particularly useful in preventing metal-catalyzed reactions and in detoxifying heavy metals. EDTA trisodium salt is stable under normal conditions but can degrade under extreme pH or temperature. It is non-toxic and generally recognized as safe (GRAS) when used in food applications. The hydrate form indicates the presence of water molecules in its crystalline structure, which can influence its solubility and stability. In laboratory settings, it is often utilized in buffer solutions and as a reagent in various biochemical assays. Overall, EDTA trisodium salt is a versatile compound with significant importance in both industrial and research contexts.
