Description

2,3,4,6-Tetra-o-Acetyl-1-S-Acetyl-1-Thio-A-D-Galactopyranoside CAS NO 130796-15-5 is a key thioglycoside derivative used as a crucial glycosyl donor and synthetic intermediate in carbohydrate chemistry. Its value lies in its role as a protected, activated galactose building block, enabling the stereoselective construction of complex oligosaccharides and glycoconjugates. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors, particularly for the development of novel glycotherapeutics, vaccines, and biochemical probes.

Application

• Glycoconjugate Synthesis: A vital glycosyl donor for the chemical and enzymatic synthesis of oligosaccharides, glycopeptides, and glycolipids.
• Pharmaceutical Intermediates: Serves as a key building block in the research and production of active pharmaceutical ingredients (APIs) targeting glycosylation-related diseases.
• Biochemical Probe Development: Used to create labeled or modified sugars for studying carbohydrate-protein interactions, enzyme mechanisms, and cell surface recognition.
• Diagnostic Reagent Manufacturing: Employed in the synthesis of carbohydrate antigens and haptens for immunoassays and diagnostic kits.
• Glycosidase Inhibitor Research: Acts as a precursor or analog in the development of potential therapeutic inhibitors for glycosidases.
• Academic & Industrial R&D: A fundamental reagent for synthetic organic chemists and glycobiologists exploring new synthetic methodologies and biological functions of carbohydrates.
