  • Applications

    2-Deoxy-D-galactose (CAS 1949-89-9) is used primarily as a building block in carbohydrate chemistry and as a precursor for the synthesis of glycosides and rare sugar derivatives; in biochemistry and enzymology, it serves as a research reagent and can function as a substrate for glycosylation assays and studies of galactose metabolism; in pharmaceutical research it is used as a chiral building block for carbohydrate-containing compounds and intermediates; in industrial R&D it supports the development of oligosaccharides and carbohydrate-based polymer materials and may serve as a reference material or probe in enzyme assays related to galactose pathways.
