Description

Threitol is a four-carbon sugar alcohol (tetritol) with significant commercial and research utility. Its value lies in its role as a versatile chiral building block and a protective agent in biochemical and pharmaceutical synthesis. This compound is essential for manufacturers and R&D laboratories in the pharmaceutical, cosmetic, and specialty chemical industries. Threitol CAS NO 7493-90-5 is particularly noted for its applications in asymmetric synthesis and as a stabilizer for sensitive biological materials.

Application

• As a chiral intermediate in the synthesis of pharmaceuticals and complex organic molecules.
• Utilized as a starting material or protective agent in carbohydrate chemistry.
• Employed in cosmetic formulations as a humectant and skin-conditioning agent.
• Acts as a cryoprotectant and stabilizer in biochemical and diagnostic reagent preparations.
• Used in research for studying enzyme mechanisms and metabolic pathways.
• Serves as a standard or reference compound in analytical chromatography (HPLC, GC).
• Potential application in the production of specialty polymers and resins.

Quality Control

Our Threitol is produced 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. A Certificate of Analysis (COA) detailing purity, identity, and specific impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

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