Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of heterocyclic compounds. It serves as a building block in the development of certain antifungal and antibacterial agents due to its reactive aldehyde and nitro groups. The bromine atom allows for further functionalization via cross-coupling reactions, making it valuable in medicinal chemistry and organic synthesis. Also employed in the production of dyes and functional materials where specific substitution patterns are required.
