The Uses of 4-Bromobenzaldehyde
4-Bromobenzaldehyde is widely utilized as an intermediate for the preparation of agrochemicals, pharmaceuticals and other organic compounds. It is used as a precursor and reacts with sulfamethoxazole to prepare Schiff?s base, 4-[(4-Bromo-benzylidene)-amino]-N-(5-methyl-isoxazol-3-yl)-benzene sulfonamide, which can be used for the photo stability of polyvinyl chloride (PVC). It plays an important role in palladium-catalyzed mono- and bis-arylation of 3,4-(ethylenedioxy)thiophenes. It is employed in a cross-coupling study with potassium vinyltrifluoroborate.
