Used primarily in the synthesis of pharmaceutical compounds, particularly in the development of drugs targeting neurological disorders. Acts as a key intermediate in the production of active pharmaceutical ingredients (APIs) for medications that modulate neurotransmitter activity. Also employed in organic chemistry research for constructing complex heterocyclic structures, which are essential in drug discovery and development processes. Its reactive chloromethyl group facilitates further chemical modifications, making it valuable in creating diverse chemical libraries for screening potential therapeutic agents.
