Description

Propane-1,2,3-Triol CAS NO 64333-26-2 is a high-purity trihydric alcohol, commonly known as glycerol, serving as a fundamental building block and versatile intermediate in advanced chemical synthesis. Its consistent quality and reliable performance are critical for manufacturers requiring precise control over reaction pathways and final product specifications. This compound is essential for industries such as pharmaceuticals, personal care, food additives, and specialty chemicals, where it functions as a humectant, solvent, and precursor.

Application

• Pharmaceutical Synthesis: Acts as a key intermediate and excipient in the production of active pharmaceutical ingredients (APIs), cough syrups, and topical formulations.
• Personal Care & Cosmetics: Used as a superior humectant and moisturizing agent in creams, lotions, soaps, and toothpaste for its hygroscopic properties.
• Food & Beverage Industry: Employed as a solvent, sweetener, and humectant (food additive E422) in confectionery, baked goods, and liqueurs.
• Chemical Manufacturing: Serves as a vital precursor for producing alkyd resins, polyurethanes, explosives (nitroglycerin), and plasticizers.
• Industrial Fluids: Utilized as a component in antifreeze, hydraulic fluids, and lubricants due to its viscosity and thermal stability.
• Tobacco Processing: Applied as a hygroscopic agent to maintain moisture and control the burning rate in cigarette production.

Quality Control

Our Propane-1,2,3-Triol is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We offer grades compliant with relevant pharmacopeial standards such as USP, EP, and BP, as well as food-grade specifications (FCC). Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a 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 performance. Keep away from strong oxidizing agents.
