Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where halogenated aromatic esters serve as building blocks. Its structure allows for selective cross-coupling reactions, making it valuable in creating complex molecules for drug discovery. Commonly employed in Suzuki and Heck reactions to form carbon-carbon bonds, enabling the construction of biaryl or substituted aromatic systems found in bioactive compounds. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and functional group compatibility.
