Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs). Its aldehyde and bromo functional groups allow for selective cross-coupling reactions and condensation processes, making it valuable in constructing complex aromatic frameworks. Commonly employed in the preparation of kinase inhibitors and anti-inflammatory agents. The tert-butyl ester group acts as a protecting group, enabling controlled deprotection during multi-step syntheses. Also utilized in agrochemical research for building fluorinated building blocks with enhanced metabolic stability.
