Description

D-Glucosamine-3-Sulfate is a specific, sulfated derivative of the fundamental amino sugar D-glucosamine, distinguished by the sulfate group at the 3-position. This targeted molecular modification is critical for enhancing bioavailability and biological activity in advanced pharmaceutical and nutraceutical formulations. It is an essential high-purity intermediate for research and production in the pharmaceutical, dietary supplement, and cosmetic industries, where precise chemical structure dictates efficacy.

Application

• Pharmaceutical Intermediate: Key starting material or active pharmaceutical ingredient (API) precursor for developing chondroprotective drugs and anti-osteoarthritis therapies.
• Dietary Supplements: Used in premium joint health and mobility formulations, where its specific sulfation pattern is leveraged for enhanced absorption and targeted action.
• Biochemical Research: Vital reagent in glycosaminoglycan (GAG) research, enzymology studies, and investigations into cartilage metabolism and repair mechanisms.
• Cosmeceuticals: Incorporated into advanced skincare products aimed at improving skin hydration and elasticity by supporting the skin's extracellular matrix.
• Veterinary Medicine: Component in high-performance supplements and treatments for joint care in companion and performance animals.

Quality Control

Our D-Glucosamine-3-Sulfate is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards suitable for pharmaceutical and nutraceutical applications. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability, consistency, 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 degradation due to moisture absorption.
