Used in biomedical research to study glycosaminoglycan degradation and enzyme activity, particularly in cartilage and connective tissue studies. Commonly employed as a standard in chromatographic and mass spectrometric analysis for identifying chondroitin sulfate fragments. Supports development of therapeutics targeting osteoarthritis and joint health due to its structural similarity to components found in human cartilage. Also utilized in cell culture applications to investigate extracellular matrix interactions and signaling pathways involved in inflammation and tissue repair.
