Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where halogenated benzyl moieties enhance biological activity. Its structure allows for selective functionalization, making it valuable in creating compounds with targeted receptor interactions. Commonly employed in the preparation of antitumor agents, antimicrobials, and central nervous system modulators. Also utilized in agrochemicals for the production of herbicides and pesticides due to its stability and reactivity in coupling reactions. Frequently serves as a building block in combinatorial chemistry and medicinal research for rapid drug discovery.
