Description

Benzyl-2-o-Toluolsulfonyl-α-D-Arabinopyranoside CAS NO 61134-28-9 is a specialized carbohydrate derivative, specifically a benzyl-protected arabinopyranoside with a toluolsulfonyl (tosyl) group at the 2-position. This compound is a critical building block (synthon) in synthetic organic chemistry, particularly for the controlled construction of complex sugar molecules and nucleoside analogs. It is primarily used by pharmaceutical R&D laboratories and fine chemical manufacturers engaged in the synthesis of antiviral agents, antibiotics, and other bioactive compounds.

Application

• Pharmaceutical Intermediate: Key starting material for the synthesis of novel nucleoside analogs with potential antiviral or anticancer activity.
• Glycochemistry Research: Used as a protected glycosyl donor or acceptor in the stereoselective synthesis of oligosaccharides and glycoconjugates.
• Chemical Biology Probes: Serves as a precursor for labeled sugar derivatives used in metabolic pathway studies and enzyme inhibition assays.
• Process Development: Employed in scaling up routes to complex carbohydrate-based active pharmaceutical ingredients (APIs).
• Academic Research: Utilized in universities and research institutes for methodological development in synthetic organic and medicinal chemistry.
• Fine Chemical Synthesis: Intermediate for producing specialty chemicals with specific chiral configurations.
