Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in creating bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to build complex aromatic systems. Also utilized in agrochemical research for designing novel pesticides with improved selectivity and efficacy. Its aldehyde group enables easy derivatization for use in Schiff base formation and other condensation reactions relevant to medicinal chemistry.
