Description

Glucosamine Sulfate is a vital amino sugar and a fundamental building block for glycosaminoglycans, which are essential components of cartilage and synovial fluid. Its primary commercial value lies in its role as a key active ingredient in dietary supplements and nutraceuticals targeting joint health and mobility support. This high-purity compound is critical for manufacturers in the pharmaceutical, nutraceutical, and functional food industries seeking reliable, quality-assured raw materials for their formulations. The product is supplied as Glucosamine Sulfate CAS NO 91674-26-9, meeting stringent quality standards for global supply chains.

Application

• Dietary Supplements & Nutraceuticals: Primary active ingredient in capsules, tablets, and powders formulated for joint comfort, osteoarthritis support, and connective tissue health.
• Pharmaceutical Intermediates: Used in the synthesis of more complex chondroprotective agents and specialized pharmaceutical formulations.
• Functional Food & Beverage Fortification: Incorporated into health drinks, meal replacements, and fortified food products to enhance their nutritional profile for joint wellness.
• Veterinary Health Products: Key component in supplements for companion animals and livestock to support joint and cartilage health.
• Cosmeceutical Preparations: Utilized in topical creams and serums aimed at skin hydration and promoting the synthesis of hyaluronic acid.
• Research & Development: Serves as a standard or reagent in biochemical research related to glycosaminoglycan synthesis, cartilage biology, and inflammatory pathways.

Quality Control

Our Glucosamine Sulfate is manufactured under a quality management system and undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for nutraceutical and pharmaceutical applications. We can supply material compliant with relevant specifications such as USP, FCC, and in-house pharmacopeial standards. A comprehensive Certificate of Analysis (COA) documenting identity, purity, assay, and impurity profiles is provided with each batch to ensure full traceability and quality assurance for our B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation. Keep away from incompatible materials.
