This compound is primarily utilized in organic synthesis as a key intermediate for the production of various pharmaceuticals and agrochemicals. Its reactive chloroethyl group allows it to participate in alkylation reactions, making it valuable in the development of drugs targeting the central nervous system, such as certain antihistamines and anticholinergic agents. Additionally, it finds application in the synthesis of quaternary ammonium compounds, which are used as surfactants, disinfectants, and phase-transfer catalysts. In research, it serves as a building block for creating more complex molecules with potential biological activity. Its use is often associated with controlled environments due to its reactive and potentially hazardous nature.
