Description

Chondroitin Disaccharide (δ-Di-Disd, Sodium Salt) is a defined, low-molecular-weight disaccharide unit derived from the enzymatic or chemical depolymerization of chondroitin sulfate. This high-purity building block is critical for research and development in glycosaminoglycan (GAG) analysis and the synthesis of novel bioactive compounds. It serves as an essential reference standard and intermediate for pharmaceutical, nutraceutical, and diagnostic applications, enabling precise study of carbohydrate-protein interactions and metabolic pathways. CAS NO 149368-03-6.

Application

• Pharmaceutical Reference Standard: Used for the identification, assay, and quality control of chondroitin sulfate and related products in compliance with pharmacopeial monographs (e.g., USP, EP).
• Biomedical Research: Serves as a critical tool for studying enzyme kinetics (e.g., chondroitinases, sulfatases), glycan biosynthesis, and the structure-activity relationships of glycosaminoglycans.
• Diagnostic Reagent Development: Employed in the formulation of calibration standards and controls for diagnostic kits targeting GAG-related disorders, such as mucopolysaccharidoses.
• Nutraceutical Ingredient Analysis: Acts as an analytical standard to verify the composition, purity, and authenticity of chondroitin sulfate used in dietary supplements.
• Glycobiology & Drug Discovery: Utilized as a precise building block for the chemical-enzymatic synthesis of defined oligosaccharides to develop new therapeutic agents.
• Cosmeceutical R&D: Applied in research to understand the fundamental mechanisms of chondroitin fragments in skin health and anti-aging formulations.
