Description

L-(-)-Arabitol is a naturally occurring sugar alcohol (alditol) with the CAS number 7643-75-6. This high-purity chiral building block is valued for its role as a key intermediate in the synthesis of pharmaceuticals, fine chemicals, and novel materials. It is essential for research and production in the pharmaceutical, nutraceutical, and specialty chemical industries, where precise stereochemistry and consistent quality are paramount.

Application

• Pharmaceutical Intermediate: A critical chiral precursor in the synthesis of antiviral drugs, nucleoside analogs, and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a standard, substrate, or carbon source in microbiological studies, enzymology, and metabolic pathway analysis.
• Food & Nutraceutical Ingredient: Serves as a low-calorie sweetener and bulking agent in specialty dietary products and functional foods.
• Cosmetic Formulations: Employed as a humectant and moisturizing agent in high-end skincare and personal care products.
• Chemical Synthesis: Acts as a versatile starting material for producing chiral ligands, catalysts, and complex organic molecules.
• Diagnostic Reagents: Utilized in the formulation of culture media and diagnostic kits for clinical and laboratory testing.
