Description

Chondroitin Sulfate Sodium Salt is a highly purified glycosaminoglycan derived from animal cartilage, widely recognized for its viscoelastic and chondroprotective properties. This essential biomaterial is critical for applications demanding high-purity, bioavailable, and consistent raw materials. It serves as a key functional ingredient for manufacturers in the pharmaceutical, nutraceutical, and advanced biomedical sectors seeking to develop products that support joint health and tissue repair.

Application

• Pharmaceutical Active Ingredient: Core component in prescription and over-the-counter (OTC) medications for osteoarthritis and joint health supplements.
• Dietary Supplements & Nutraceuticals: Used in capsules, tablets, and powdered blends for human and veterinary joint support formulas.
• Cosmeceuticals & Skincare: Incorporated into topical formulations for its moisturizing properties and to support skin elasticity.
• Biomedical Research & Cell Culture: Utilized as a substrate or supplement in studies involving cartilage engineering, stem cell differentiation, and extracellular matrix (ECM) research.
• Veterinary Medicine: Active component in injectable and oral treatments for companion animals and livestock to manage joint disorders.
• Functional Foods & Beverages: Added to fortified foods and drinks designed to promote musculoskeletal wellness.

Quality Control

Our Chondroitin Sulfate Sodium Salt is manufactured under strict quality systems. We offer grades compliant with major pharmacopoeial standards, including USP and EP, as well as FCC for food applications. Every batch undergoes rigorous identity, purity, and potency testing via methods such as HPLC, IR spectroscopy, and specific rotation. Certificates of Analysis (COA) documenting assay, sulfate content, protein residue, heavy metals, and microbiological limits are available upon request to ensure full traceability and compliance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at controlled room temperature (15-25°C). For long-term stability, consider storage under desiccant or in a low-humidity environment to prevent caking and degradation.
