Description

L-(-)-Arabitol is a naturally occurring sugar alcohol (alditol) with the CAS number 7843-75-6, valued for its role as a chiral building block and low-calorie sweetener. This compound is significant for its applications in pharmaceutical synthesis, food science, and as a standard in biochemical research. It is primarily needed by manufacturers and R&D teams in the pharmaceutical, nutraceutical, and food & beverage industries seeking high-purity, specialized carbohydrate intermediates.

Application

• Pharmaceutical Intermediate: Used as a chiral precursor in the synthesis of antiviral drugs and other active pharmaceutical ingredients (APIs).
• Food & Beverage Additive: Functions as a low-calorie bulk sweetener and texturizer in sugar-free and diabetic-friendly products.
• Biochemical Research: Serves as a standard or substrate in metabolic pathway studies, enzymology, and microbiology.
• Cosmetics & Personal Care: Acts as a humectant and moisturizing agent in skin care formulations.
• Microbial Fermentation Studies: Used in research to study pentitol metabolism in yeasts and bacteria.
• Diagnostic Reagents: Employed in the formulation of specific culture media and diagnostic kits.

Quality Control

Our L-(-)-Arabitol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade specifications suitable for pharmaceutical and food applications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
