Description

Chondroitin Sulfate CAS NO 9007-28-7 is a sulfated glycosaminoglycan (GAG) composed of alternating sugars, N-acetylgalactosamine and glucuronic acid, which is a vital structural component of cartilage and connective tissues. Its primary commercial value lies in its ability to support joint health, retain moisture, and provide structural integrity in various formulations. This high-purity ingredient is essential for manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries seeking reliable, bioactive raw materials.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in joint health formulas, capsules, and tablets aimed at supporting cartilage structure and joint mobility.
• Pharmaceuticals: Used in the formulation of prescription and over-the-counter (OTC) drugs for osteoarthritis and as a component in wound healing preparations.
• Cosmetics & Skincare: Incorporated into anti-aging serums, moisturizers, and creams for its exceptional hydrating and skin-plumping properties.
• Veterinary Medicine: Formulated into pet supplements and treatments to support joint health in dogs, cats, and horses.
• Functional Foods & Beverages: Added to fortified foods and drinks designed to deliver joint support benefits.
• Biomedical Research & Cell Culture: Serves as a substrate or component in studies involving cartilage regeneration, tissue engineering, and cell biology.

Quality Control

Our Chondroitin Sulfate is manufactured under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, potency, and safety, aligning with relevant pharmacopeial standards such as USP and EP. A comprehensive Certificate of Analysis (COA) documenting assay, sulfate 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 product 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.
