Description

Methyl 3,4-Di-o-Benzyl-A-D-Mannopyranoside CAS NO 79218-87-4 is a protected carbohydrate derivative, specifically a benzylated methyl mannoside, serving as a crucial chiral building block and synthetic intermediate. Its value lies in providing a chemically stable mannose scaffold where the 3 and 4 hydroxyl groups are selectively protected, enabling precise downstream functionalization. This compound is essential for researchers and manufacturers in pharmaceutical development, particularly for synthesizing complex glycoconjugates, oligosaccharides, and novel therapeutic agents.

Application

• Glycochemistry & Glycobiology Research: A key intermediate for the synthesis of complex oligosaccharides, glycoconjugates, and glycomimetics.
• Pharmaceutical Intermediate: Used in the development of carbohydrate-based drugs, including antiviral agents, antibiotic adjuvants, and cancer therapeutics.
• Chemical Biology Probes: Serves as a precursor for labeled sugars (e.g., fluorescent, radioactive) used to study glycosylation processes and carbohydrate-protein interactions.
• Enzyme Substrate & Inhibitor Synthesis: Employed to create substrates or inhibitors for glycosidases and glycosyltransferases for biochemical assays.
• Material Science: Potential monomer for creating novel bio-based polymers and surfactants with specific stereochemistry.
• Standards & Reference Materials: Provides a high-purity standard for analytical method development and quality control in carbohydrate chemistry.
