Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active molecules. Its bromine functionality allows for further cross-coupling reactions, such as Suzuki or Heck couplings, enabling the introduction of aromatic or heteroaromatic systems. The tert-butyl ester group offers stability during multi-step syntheses and can be easily deprotected under acidic conditions to yield the corresponding carboxylic acid for further derivatization. Commonly employed in medicinal chemistry for constructing pyridine-based scaffolds with targeted biological activity.
