Application

3,5-Dibromobenzaldehyde serves as a key building block in the synthesis of brominated pharmaceutical intermediates and liquid crystal materials. It is widely used in palladium-catalyzed cross-coupling reactions to construct complex biaryl structures for drug discovery. The compound also finds applications in the development of organic electronic materials due to its electron-withdrawing bromine groups. Researchers utilize it to prepare ligands for catalysis and as a precursor in the synthesis of antifungal and antibacterial agents.
