Description

Propanediol CAS NO 26264-14-2 is a high-purity, versatile diol compound widely used as a key intermediate and functional ingredient in advanced chemical synthesis. Its bifunctional nature, featuring two reactive hydroxyl groups, makes it an essential building block for creating polymers, resins, and specialty chemicals with tailored properties. This product is particularly valuable for manufacturers in the pharmaceutical, personal care, and industrial coatings sectors seeking a reliable and consistent raw material for their formulations.

Application

• Polymer & Resin Production: Serves as a monomer or chain extender in the synthesis of unsaturated polyester resins (UPR), polyurethanes (PU), and alkyd resins, imparting flexibility and durability.
• Pharmaceutical Intermediates: Used as a crucial starting material or solvent in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Personal Care & Cosmetics: Functions as a humectant, solvent, and viscosity modifier in skin creams, lotions, serums, and other cosmetic formulations.
• Industrial Coatings & Inks: Acts as a reactive diluent and cross-linking agent in high-performance coatings, adhesives, and printing inks, enhancing film properties.
• Chemical Synthesis: A versatile intermediate for producing plasticizers, lubricants, and other specialty organic compounds.
• Antifreeze & Deicing Fluids: Used as a base component in less toxic, biodegradable antifreeze and aircraft deicing formulations.
