Description

D(+)-Xylose is a naturally occurring pentose sugar, also known as wood sugar, with the CAS registry number 58-86-6. This high-purity monosaccharide is a versatile chiral building block and a key intermediate in numerous biochemical and industrial processes. It is essential for manufacturers and researchers in the pharmaceutical, food science, and biotechnology sectors seeking a reliable source of a fundamental carbohydrate.

Application

• Pharmaceutical Intermediate: Used in the synthesis of nucleoside analogs, antiviral drugs, and other active pharmaceutical ingredients (APIs).
• Diagnostic Agent: Serves as the active component in the D-xylose absorption test for diagnosing malabsorption syndromes.
• Food & Flavor Industry: Acts as a low-calorie sweetener, a prebiotic dietary fiber, and a precursor for flavor compounds like furfural.
• Microbiological Culture Media: Provides a defined carbon source for the fermentation and cultivation of specific microorganisms.
• Biochemical Research: Employed as a standard and substrate in enzymatic studies, carbohydrate metabolism research, and glycobiology.
• Chemical Synthesis: Utilized as a starting material for producing xylitol, surfactants, and other sugar-derived chemicals.
