Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and central nervous system agents. Its structure allows for selective functionalization, making it valuable in constructing complex molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form biaryl systems. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated aromatic framework. The ester group facilitates further derivatization, enabling the introduction of amide or alcohol functionalities in target compounds.
