Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require substituted benzaldehyde derivatives. Its structure allows for selective functionalization, making it valuable in creating complex organic molecules. Commonly employed in the development of agrochemicals, including herbicides and fungicides, due to its reactivity in carbon-carbon bond-forming reactions. Also utilized in the preparation of fragrances and dyes, where the aldehyde group enables condensation reactions to form aromatic Schiff bases or other conjugated systems. Its bromo and methyl substituents provide sites for cross-coupling reactions, enhancing its utility in medicinal chemistry and materials science.
