Used primarily as an intermediate in organic synthesis, especially in pharmaceutical manufacturing. It serves as a building block for active pharmaceutical ingredients (APIs) due to its reactive chloroacetyl group, which readily undergoes nucleophilic substitution. Commonly employed in the preparation of amide derivatives and heterocyclic compounds. Its pyrrolidine ring enhances solubility and bioavailability in drug candidates, making it valuable in the development of central nervous system agents and enzyme inhibitors. Also utilized in agrochemical synthesis for creating herbicides and plant growth regulators.
