Description

D-Xylose is a naturally occurring five-carbon aldose sugar, also known as wood sugar, with the CAS registry number 6763-34-4. This versatile monosaccharide serves as a critical building block and precursor in numerous biochemical and industrial processes. It is essential for manufacturers and researchers in the pharmaceutical, food and beverage, and nutraceutical industries seeking high-purity, reliable raw materials.

Application

• Pharmaceutical Intermediate: A key starting material for the synthesis of various therapeutic agents and as a component in diagnostic tests, such as the D-xylose absorption test for intestinal function.
• Prebiotic & Nutraceutical Ingredient: Used in dietary supplements and functional foods to promote the growth of beneficial gut microbiota (e.g., Bifidobacteria).
• Food & Beverage Additive: Employed as a low-calorie sweetener, flavor enhancer, and texturizing agent in specialty food products.
• Microbiological Culture Media: Serves as a selective carbon source in fermentation processes and for cultivating specific microorganisms in industrial biotechnology.
• Chemical Synthesis: A renewable platform chemical for producing derivatives like xylitol, furfural, and other value-added compounds via catalytic processes.
• Animal Feed Supplement: Incorporated into feed formulations to improve digestive health and nutrient absorption in livestock.
