  • Applications

    L-Xylose (CAS 609-06-3) is a pentose sugar that can be converted in a range of industrial pathways. In chemical manufacturing, it serves as a starting material for acid-catalyzed dehydration to furfural, yielding furfural and furan-derived derivatives that underpin resins, solvents, and specialty chemicals. At the same time, L-Xylose is hydrogenated to form xylitol, a low-calorie sugar alcohol used as a substitute sweetener and as a precursor for material and formulation applications. Fermentation systems can use L-Xylose as a carbon source to produce value-added biochemicals such as organic acids and pentose-derived fermentation products. Additionally, L-Xylose provides a feedstock for pentose-based biorefineries to synthesize furans and derivatives for the chemical and polymer industries. In chemical synthesis, it can be converted to sugar derivatives (esters and ethers) for polymer and other chemical applications. Applications are subject to local regulations and formulation constraints.
