Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted benzaldehyde derivatives. Its bromo and aldehyde functional groups allow for selective reactions, making it valuable in cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in the production of dyes, fragrances, and specialty organic compounds where halogenated aromatic structures enhance stability or reactivity. Also utilized in research settings for building complex molecules in medicinal chemistry due to its versatile reactivity profile.
