Description

D-Xylose is a naturally occurring pentose sugar, also known as wood sugar, with the CAS registry number 31178-70-8. This versatile monosaccharide is a critical intermediate in carbohydrate metabolism and serves as a fundamental building block for various high-value biochemicals. It is essential for manufacturers and researchers in the food, pharmaceutical, and biotechnology industries seeking natural sweeteners, prebiotics, or platform chemicals for green chemistry.

Application

• Food & Beverage Industry: Used as a low-calorie sweetener and a prebiotic dietary fiber to promote gut health.
• Pharmaceutical Intermediates: Serves as a key chiral starting material for synthesizing nucleoside analogs and other active pharmaceutical ingredients (APIs).
• Diagnostic Reagents: Employed in medical diagnostic kits, most notably for the D-xylose absorption test to assess intestinal malabsorption.
• Microbial Fermentation: Acts as a fermentable carbon source in industrial biotechnology for producing biofuels (e.g., xylitol, ethanol) and organic acids.
• Cell Culture Media: Utilized as a component in specialized cell culture and microbiological media formulations.
• Chemical Synthesis: A renewable platform chemical for producing furfural, a valuable solvent and resin precursor.

Quality Control

Our D-Xylose is produced under a stringent quality management system. We offer grades compliant with major pharmacopoeial standards, including USP-NF, Ph. Eur., and JP, as well as Food Chemical Codex (FCC) for food applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

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); ensure the container is kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
