Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and anti-inflammatory drugs. It plays a role in the preparation of dyes and fragrances due to its aromatic aldehyde structure. Also utilized in organic research for introducing bromo-substituted aromatic systems in cross-coupling reactions. Its aldehyde group allows for transformations into acids, alcohols, or imines, making it valuable in multi-step synthesis of complex molecules.
