Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its aldehyde and hydroxymethyl functional groups allow for diverse chemical modifications, making it valuable in constructing complex organic structures. Commonly employed in cross-coupling reactions due to the bromine substituent, it facilitates the formation of carbon-carbon bonds in drug discovery pathways. Also utilized in the preparation of fluorescent probes and specialty polymers owing to its reactive sites and aromatic backbone.
