(R)-(-)-Epichlorohydrin is a high-value chiral building block widely used in pharmaceutical, fine chemical, and material synthesis. Its unique chiral epoxy and chloromethyl groups enable highly selective ring-opening reactions, making it indispensable for producing enantiomerically pure compounds. In pharmaceutical R&D, it serves as a key intermediate for synthesizing stable prostacyclin (PGI?) analogs like UT-15, chiral morpholines, dioxanes, and trans-2,4-disubstituted piperidines—core scaffolds for anti-inflammatory, cardiovascular, and central nervous system drugs. It is also critical for manufacturing chiral surfactants, epoxy resins, and ion-exchange resins, as well as for fiber treatment agents. In asymmetric synthesis, it is used in Mitsunobu diol-cyclization reactions to construct complex heterocyclic frameworks. With its high reactivity and chiral purity, (R)-(-)-Epichlorohydrin bridges natural terpene resources and industrial chiral synthesis, supporting scalable production of high-purity pharmaceuticals and specialty chemicals.

(R)-(-)-Epichlorohydrin is a Danger class hazardous substance (GHS02, GHS05, GHS06, GHS08) with severe risks: flammable liquid/vapor (H226), toxic if swallowed/skin contact/inhaled (H301/H311/H331), causes severe skin burns and eye damage (H314), skin sensitizer (H317), and suspected carcinogen (H350). Inhalation of vapor/mist irritates the respiratory tract, causing coughing, shortness of breath, or pulmonary edema. Skin contact leads to redness, blistering, or chemical burns; eye contact may cause corneal damage or blindness. Handle in a fume hood with chemical-resistant gloves, safety goggles, face shield, and ABEK respirator. Avoid ignition sources (sparks, open flames) and static electricity. Store sealed in a cool, dark place away from incompatible substances. In case of leakage, absorb with sand and dispose as hazardous waste. Rinse skin with soap/water for 15 minutes; flush eyes with water for 15 minutes and seek immediate medical attention.
