Used as an intermediate in the synthesis of functionalized polymers and crosslinking agents, particularly in the production of specialty resins and elastomers. It serves in the preparation of quaternary ammonium compounds, which find use as antimicrobial agents, surfactants, and fabric softeners. Its bifunctional structure allows for controlled alkylation reactions, making it valuable in organic synthesis for introducing aromatic and alkyl chloride functionalities in pharmaceuticals, agrochemicals, and ionic liquids.
