Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor modulators and kinase inhibitors. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems due to the presence of reactive bromo and ester functional groups. Facilitates cross-coupling reactions such as Suzuki or Heck reactions, enabling the introduction of aryl or alkenyl moieties. Also utilized in agrochemical research for designing novel pesticides with improved biological activity. Its methyl ester group can be hydrolyzed to yield carboxylic acid derivatives for further functionalization.
