Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antitumor and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems. Commonly employed in Suzuki and other cross-coupling reactions to form biaryl derivatives with biological activity. Also utilized in agrochemical research for designing new pesticidal agents due to its halogenated aromatic and reactive chloromethyl group.
