(R)-(−)-Epichlorohydrin is primarily used in the synthesis of chiral compounds and pharmaceuticals. Its application is crucial in the production of enantiomerically pure drugs, where the specific stereochemistry of the molecule is essential for biological activity. It serves as a key intermediate in the manufacture of beta-blockers, which are important in treating cardiovascular diseases. Additionally, it is utilized in the preparation of epoxy resins, which are then used in coatings, adhesives, and composites, providing enhanced performance and durability. The chemical is also employed in the development of advanced materials, such as ion-exchange resins and water treatment chemicals, due to its reactivity and ability to form stable polymers.
