Description

Chondroitin 4-Sulfate CAS NO 24967-93-9 is a specific, sulfated glycosaminoglycan (GAG) derived from natural sources, essential for maintaining the structural integrity and hydration of connective tissues. This high-purity grade is critical for research and development in life sciences and for formulating advanced nutraceutical and pharmaceutical products. It is primarily sought by manufacturers in the dietary supplement, biomedical research, and cosmetic industries for its targeted bioactivity.

Application

• Biomedical & Pharmaceutical Research: Used as a standard or active component in studies of cartilage metabolism, osteoarthritis, and extracellular matrix biology.
• Nutraceutical Formulations: A key ingredient in high-quality joint health supplements, often combined with glucosamine.
• Cosmeceuticals: Incorporated into advanced skincare products for its purported hydrating and skin-repair properties.
• Cell Culture & Tissue Engineering: Serves as a substrate or media supplement to support the growth and differentiation of chondrocytes and other specialized cells.
• Diagnostic Reagents: Utilized in the development of assays and kits for detecting specific enzymes or biomarkers related to GAG metabolism.
• Drug Delivery Systems: Investigated for its potential as a biocompatible carrier or targeting moiety in novel therapeutic formulations.
