Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. It reacts readily with nucleophiles due to the activated carbonyl group adjacent to the chlorine, making it valuable for constructing complex molecules. Commonly employed in the synthesis of bioactive agents, including central nervous system modulators and antipsychotic drugs. Its reactivity allows for efficient introduction of piperidine moieties into target structures, which are prevalent in many medicinal agents. Also utilized in the development of agrochemicals and functionalized heterocyclic compounds.
