Disodium EDTA dihydrate

Description:
Disodium EDTA dihydrate, with the CAS number 6381-92-6, is a chelating agent widely used in various applications, including pharmaceuticals, cosmetics, and food preservation. It is the disodium salt of ethylenediaminetetraacetic acid (EDTA) and exists as a dihydrate, meaning it contains two water molecules in its crystalline structure. This compound is characterized by its ability to form stable complexes with metal ions, effectively sequestering them and preventing undesirable reactions, such as oxidation. Disodium EDTA dihydrate is typically a white, crystalline powder that is soluble in water, making it easy to incorporate into various formulations. Its pH is generally neutral to slightly alkaline, which contributes to its compatibility with a range of substances. In biological systems, it can be used to treat heavy metal poisoning by binding to toxic metals and facilitating their excretion. Additionally, it is recognized for its role in enhancing the stability and efficacy of certain active ingredients in formulations. Overall, Disodium EDTA dihydrate is valued for its versatility and effectiveness as a chelating agent.
