Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for drugs targeting inflammation and central nervous system disorders. It serves as a building block in organic reactions, especially in cross-coupling reactions like Suzuki and Heck couplings, enabling the formation of carbon-carbon bonds for complex molecule assembly. Also employed in the production of agrochemicals, such as herbicides and fungicides, due to its reactivity and functional group compatibility. Its bromine and aldehyde functionalities allow for selective modifications, making it valuable in research and development of new bioactive compounds.
