Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted benzaldehyde derivatives. Its structure allows for selective functionalization in multi-step organic reactions, including cross-coupling reactions like Suzuki and Heck couplings due to the bromine substituent, making it valuable in creating complex molecules with carbon-carbon bond formation. Commonly employed in the production of dyes, fragrances, and UV stabilizers due to its reactivity and ability to form conjugated systems. Also utilized in research for designing novel compounds with biological activity, including antimicrobial and anti-inflammatory agents.
