Description
Disodium galactarate (CAS 1955-73-3) is a high-purity sodium salt of galactaric acid (mucic acid), with the molecular formula C6H8Na2O8. This white crystalline powder is widely utilized in biochemical and pharmaceutical research due to its role as a chelating agent and intermediate in organic synthesis. Its IUPAC name, disodium;(2S,3R,4S,5R)-2,3,4,5-tetrahydroxyhexanedioate, reflects its stereochemistry, making it valuable for chiral synthesis and carbohydrate chemistry applications. With a purity grade of ≥98%, it is suitable for analytical standards, enzymatic studies, and polymer research. Packaged under inert conditions to ensure stability, this product is ideal for laboratories requiring precise control over hygroscopic compounds.
