Applications
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.

Solubility
Soluble in ethanol and benzene. Insoluble in water.

Notes
Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong bases, strong oxidizing agents and strong reducing agents.
