Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical industries. The aldehyde and bromo functional groups allow for diverse transformations such as cross-coupling reactions, nucleophilic substitutions, and condensation reactions. Commonly employed in the preparation of heterocyclic compounds and complex aromatic structures. Its ester group can be hydrolyzed to yield carboxylic acid derivatives, enabling further chain elongation or cyclization. Suitable for constructing building blocks in drug discovery and development.
