1,2,3,4-Di-O-isopropylidene-α-D-galacturonic acid（Cat No.:L020635）is a protected derivative of D-galacturonic acid, in which the hydroxyl groups at the 1, 2, 3, and 4 positions are masked with isopropylidene (acetal) groups. This protection enhances stability and solubility in organic solvents, making it valuable for glycosylation reactions and carbohydrate-based synthesis. The compound retains the uronic acid functionality at the 6-position, allowing further modification through esterification or amidation. It serves as a key intermediate in the synthesis of complex oligosaccharides, glycomimetics, and bioactive carbohydrate derivatives used in medicinal and material chemistry.
