Description

2-Chloropropane-1,3-Diol is a versatile chlorinated diol intermediate of significant importance in fine chemical synthesis. Its bifunctional structure, featuring both a chloromethyl group and two hydroxyl groups, makes it a valuable building block for the production of more complex molecules. This compound is particularly relevant for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce chlorohydrin or polyol functionalities. We supply high-purity 2-Chloropropane-1,3-Diol CAS NO 497-04-1 to support global research and industrial production with reliable quality and consistent supply.

Application

• Pharmaceutical Intermediate: Key starting material or building block in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Modifier: Serves as a monomer or cross-linking agent in the production of specialty epoxy resins, polyurethanes, and coatings.
• Chemical Research & Development: A valuable reagent in organic synthesis laboratories for introducing chlorohydrin groups.
• Surfactant & Emulsifier Production: Intermediate in the synthesis of non-ionic surfactants and emulsifying agents.
• Flavor & Fragrance Industry: Potential precursor in the synthesis of certain aroma chemicals (subject to purity and regulatory compliance).
