Description

(2S,4S,5R,6R)-5-acetamido-2-[[(2R,3R,4S,5R,6S)-6-[(2R,3S,4R,5R)-5-acetamido-4,6-dihydroxy-2-(hydroxymethyl)oxan-3-yl]oxy-3,4,5-trihydroxyoxan-2-yl]methoxy]-4-hydroxy-6-[(1R,2R)-1,2,3-trihydroxypropyl]oxane-2-carboxylic acid is a complex, high-purity carbohydrate derivative with significant value in advanced research and pharmaceutical development. This compound serves as a critical building block or reference standard for synthesizing and studying sophisticated glycoconjugates and sialylated structures. It is primarily needed by pharmaceutical R&D teams, academic research institutions, and biotechnology companies focused on glycobiology, vaccine development, and novel therapeutic agents.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of novel glycoprotein-based drugs and biologics.
• Glycobiology Research: Used as a standard or substrate in enzymatic studies, pathway analysis, and the investigation of carbohydrate-protein interactions.
• Vaccine Adjuvant Development: Investigated for its potential role in modulating immune responses as part of conjugate vaccine platforms.
• Diagnostic Reagent Synthesis: Employed in the creation of specialized probes and ligands for diagnostic assays targeting specific carbohydrate epitopes.
• Enzymology Studies: Acts as a substrate for glycosyltransferases, sialidases, and other enzymes involved in carbohydrate metabolism.
• Reference Standard: Provides a high-purity benchmark for analytical method development, quality control, and regulatory submissions in pharmaceutical manufacturing.
