Description

Chondroitin Sulfate Sodium Salt Bovine(Rg) is a highly purified glycosaminoglycan derived from bovine cartilage, serving as a critical raw material for the nutraceutical and pharmaceutical industries. Its primary value lies in its role as a key structural component of connective tissues, supporting joint health and cartilage integrity. This product is essential for manufacturers of dietary supplements, functional foods, and advanced drug delivery systems targeting osteoarthritis and other musculoskeletal conditions.

Application

• Dietary Supplements & Nutraceuticals: A core ingredient in joint health formulas, capsules, and tablets aimed at supporting cartilage structure and reducing inflammation.
• Pharmaceutical Intermediates: Used in the development and production of prescription and over-the-counter (OTC) medications for osteoarthritis and other degenerative joint diseases.
• Functional Food & Beverage Fortification: Incorporated into health drinks, yogurts, and other food products to provide added joint support benefits.
• Cosmeceuticals & Topical Formulations: Utilized in anti-aging creams, serums, and wound healing ointments for its skin hydration and tissue repair properties.
• Veterinary Medicine: A key component in supplements and treatments for companion animals and livestock to support joint and bone health.
• Biomedical Research & Cell Culture: Employed as a substrate or component in studies of cartilage biology, tissue engineering, and regenerative medicine.

Quality Control

Our Chondroitin Sulfate Sodium Salt is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and potency, aligning with major pharmacopeial standards such as USP and EP. A comprehensive Certificate of Analysis (COA) detailing assay, specific rotation, protein content, heavy metals, and microbiological limits is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect stability and flow properties.
