Description

D-Galactonic Acid CAS NO 576-36-3 is a key sugar acid derived from the oxidation of galactose, serving as a vital chiral building block and intermediate in organic synthesis. Its significance lies in its role as a precursor for synthesizing complex carbohydrates, vitamin C analogs, and various bioactive compounds. This high-purity intermediate is essential for research and production in the pharmaceutical, nutraceutical, and fine chemical industries, where precise molecular structure is critical.

Application

• Pharmaceutical Intermediate: A crucial chiral precursor for the synthesis of ascorbic acid (Vitamin C) analogs, antiviral drugs, and other bioactive molecules.
• Biochemical Research: Used as a standard, substrate, or intermediate in enzymatic studies, metabolic pathway analysis, and glycobiology research.
• Fine Chemical Synthesis: Serves as a building block for producing specialty surfactants, complex carbohydrates (glycans), and chelating agents.
• Nutraceutical Development: Employed in the research and production of advanced dietary supplements and functional food ingredients.
• Cosmetic Ingredients: Acts as a starting material for synthesizing mild, sugar-based α-hydroxy acids (AHAs) for skincare formulations.
• Chemical Derivatization: Used to modify surfaces or molecules for analytical purposes, such as in chromatography or sensor development.
