Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted benzaldehyde scaffolds. Its functional groups enable selective reactions for constructing complex molecules, such as in the preparation of analgesics, anti-inflammatory agents, and certain herbicides. Commonly employed in organic synthesis for cross-coupling reactions, including Suzuki and Heck reactions, due to the presence of the bromine atom, which facilitates carbon-carbon bond formation. Also utilized in the production of fragrances and dyes where specific substitution patterns are required for desired sensory or optical properties.
