Description

Chondroitin Sulfate Shark Cartilage(Rg) is a high-purity glycosaminoglycan (GAG) derived from shark cartilage, known for its high molecular weight and specific biological activity. This compound is a critical raw material valued for its role in supporting joint health, tissue structure, and cellular communication. It is primarily sought by manufacturers in the pharmaceutical, nutraceutical, and cosmeceutical industries for the production of dietary supplements, functional foods, and advanced biomedical materials.

Application

• Pharmaceuticals: Active pharmaceutical ingredient (API) in prescription and over-the-counter (OTC) medications for osteoarthritis and joint health management.
• Dietary Supplements & Nutraceuticals: Key component in capsules, tablets, and powdered blends aimed at supporting cartilage integrity and reducing joint discomfort.
• Functional Foods & Beverages: Fortification agent in health drinks, dairy products, and snacks to provide joint support benefits.
• Cosmeceuticals & Skincare: Ingredient in anti-aging formulations, serums, and creams for its moisturizing and skin-repair properties.
• Veterinary Medicine: Used in supplements and treatments for companion animals and livestock to support joint and bone health.
• Biomedical Research: Utilized in cell culture, tissue engineering, and studies on extracellular matrix (ECM) components and chondrogenesis.

Quality Control

Our Chondroitin Sulfate Shark Cartilage(Rg) is produced 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. Comprehensive Certificates of Analysis (COA) documenting all test results are provided to guarantee traceability and batch-to-batch consistency.

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 to prevent absorption of atmospheric moisture.
