Cas no 21193-75-9 (d-Galactal)
d-Galactal is a valuable carbohydrate derivative widely used in organic synthesis and glycochemistry. It serves as a key intermediate for the preparation of glycosides, oligosaccharides, and other galactose-containing compounds. The compound features a reactive double bond at the C1-C2 position, enabling selective functionalization through glycosylation, oxidation, or reduction reactions. Its stability and well-defined stereochemistry make it particularly useful for studying enzyme mechanisms, such as glycosidase inhibition, and for developing glycomimetics. d-Galactal is also employed in the synthesis of bioactive molecules, including antiviral and anticancer agents. Its versatility and reliability in synthetic applications underscore its importance in both academic and industrial research settings.
