Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the construction of complex aromatic systems. Its halogen substituents allow for selective cross-coupling reactions, such as Suzuki or Ullmann reactions, enabling the introduction of various functional groups. The tert-butyl ester group acts as a protected carboxylic acid, which can be deprotected under mild acidic conditions to release the corresponding benzoic acid derivative. This makes the compound valuable in multi-step organic syntheses where controlled reactivity and functional group compatibility are required.
