1,2,3,4,6-Penta-O-acetyl-alpha-D-galactopyranose from TCI (product code P3253) is a galactose derivative in which every hydroxyl group has been acetylated, with an alpha configuration at the anomeric carbon. It is one of the most common starting materials in carbohydrate chemistry and glycoscience. In the laboratory, protected sugars like this one serve as precursors to glycosyl donors. Researchers use them to build galactosides, oligosaccharides and glycoconjugates, which matter in studies of cell recognition, in immunology and in the development of carbohydrate-based drugs.

Its main advantage is that acetyl groups protect all of the hydroxyl positions. This makes the sugar more soluble in organic solvents and easier to purify than free galactose. The acetylated anomeric position can be activated selectively, for example by converting it into a glycosyl halide or a thioglycoside, which allows glycosidic bonds to form in a controlled way. The acetyl groups can also be removed under commonly used deacetylation conditions. Because its stereochemistry is clearly defined, the compound is a reliable starting point for stepwise synthesis, where predictable outcomes at each stage are essential.

In Indonesia, this compound is useful to researchers working in natural product chemistry, medicinal chemistry and chemical biology. University research groups, pharmaceutical research and development teams, and institutional laboratories can use it as a dependable building block for carbohydrate synthesis projects. These include glycoside preparation, oligosaccharide assembly and glycoconjugate studies. Sourcing it through AMI Scientific gives local laboratories access to a recognised TCI reagent for both teaching-oriented synthesis and advanced glycoscience research programmes.

Related TCI products

Glycosyl donor preparation: the acetylated anomeric position can be selectively converted into glycosyl halides or thioglycosides, giving activated donors for controlled glycosylation reactions.
Galactoside synthesis: the fully protected galactose framework and defined alpha stereochemistry give a reliable starting point for building galactoside targets step by step.
Oligosaccharide assembly: as a protected galactose unit, it helps researchers build longer sugar chains while keeping the remaining hydroxyl groups masked until deprotection is needed.
Glycoconjugate research: it supports the preparation of galactose-containing conjugates used in studies of cell recognition, immunology and carbohydrate-mediated biological interactions.
Carbohydrate-based drug development: it suits medicinal chemistry programmes that need a well-defined, protected sugar precursor which handles easily in organic solvents and purifies readily.
