Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its bromo functional group allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex organic molecules. The tert-butyl ester group offers steric protection and can be easily deprotected under mild acidic conditions, making it valuable in multi-step synthesis. Commonly employed in the development of active pharmaceutical ingredients (APIs) where controlled reactivity and selective transformations are required.
