Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinamide-based drugs and kinase inhibitors. It serves as a building block in agrochemicals for creating novel pesticides and herbicides due to its reactive functional groups. The bromo and amino moieties allow for selective cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the preparation of fluorescent dyes and optoelectronic materials owing to its conjugated nitrile and heterocyclic structure.
