Description

DL-Threitol is a versatile four-carbon sugar alcohol (tetritol) with the CAS registry number 6968-16-7. This achiral stereoisomer of erythritol serves as a valuable chiral building block and biochemical intermediate in advanced synthesis. It is particularly critical for industries requiring high-purity, well-characterized fine chemicals for research and production. Key applications span pharmaceutical development, cosmetic formulations, and as a standard in analytical chemistry.

Application

• Pharmaceutical Intermediate: Used in the synthesis of nucleoside analogs, antiviral drugs, and other active pharmaceutical ingredients (APIs).
• Biochemical Research: Acts as a standard or reagent in enzymatic studies, metabolic pathway analysis, and as a component in cell culture media.
• Cosmetics & Personal Care: Functions as a humectant and moisturizing agent in skin care products due to its hygroscopic properties.
• Food Science: Employed as a low-calorie sweetener and texturizing agent in specialty food products (subject to appropriate grade and regulatory approval).
• Chemical Synthesis: Serves as a starting material or chiral template for the production of more complex organic compounds and ligands.
• Analytical Chemistry: Used as a calibration standard in chromatographic methods like HPLC and GC for sugar alcohol analysis.

Quality Control

Our DL-Threitol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for research and industrial applications. We provide Certificates of Analysis (COA) with key parameters including assay, optical rotation, and impurity profiles. Specifications can be aligned with customer requirements for specific applications, including potential compliance with USP, FCC, or ACS guidelines 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 each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
