Description

L-(-)-Mannose is a naturally occurring monosaccharide, specifically the L-enantiomer of mannose. This high-purity sugar isomer is a critical building block and chiral intermediate in pharmaceutical synthesis and advanced biochemical research. It is essential for industries requiring precise stereochemistry, such as in the development of antiviral drugs, diagnostic reagents, and complex carbohydrate chemistry. Our supply ensures consistent quality and reliable availability for demanding global B2B applications.

Application

• Pharmaceutical Intermediate: Key chiral starting material for the synthesis of nucleoside analogs and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used in enzymatic studies, metabolic pathway analysis, and as a substrate for glycosyltransferases.
• Diagnostic Reagents: Component in the formulation of culture media and testing kits for microbiological and clinical diagnostics.
• Glycobiology & Glycochemistry: Fundamental substrate for the chemoenzymatic synthesis of oligosaccharides, glycoconjugates, and glycan arrays.
• Food & Nutritional Science: Employed in research on prebiotics, sweeteners, and the study of carbohydrate metabolism.
• Cosmetic Ingredients: Used in the development of advanced skincare formulations for its moisturizing and skin-conditioning properties.
