Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its aldehyde and bromo functional groups allow for versatile chemical modifications, making it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles. Commonly employed in cross-coupling reactions and condensation processes to build complex molecules with potential antitumor, antiviral, or anti-inflammatory activity. Also utilized in agrochemical research for designing novel active ingredients.
