  • Applications

    C-beta-D-xylopyranoside-2-hydroxypropane (CAS 439685-79-7) can serve as a glycoside building block and intermediate in chemical synthesis. In practical applications, it may be used in cosmetics and personal care as a humectant or stabilizing fragment; in perfumery and flavor contexts as a glycoside precursor or fragrance-release contributor; in polymers and plastics as a hydrophilic segment for glycosylated materials or as a functional modifier; in pharmaceutical R&D as a glycosylated scaffold or intermediate for drug development; and in cleaning and household formulations as a potential surfactant or solubilizing agent. Its use will depend on local regulations and formulation limits.
