Used in the synthesis of heterocyclic compounds for pharmaceutical applications, particularly as an intermediate in developing kinase inhibitors and anti-cancer agents. It serves as a building block in medicinal chemistry due to its ability to form fused ring systems like benzimidazoles and quinoxalines, which are common scaffolds in drug design. Also employed in the development of fluorescent probes and sensors owing to its favorable derivatization properties and interaction with metal ions. Its amide and amine functionalities allow for easy modification in multi-step organic syntheses.
