Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. It serves as a building block for heterocyclic compounds like quinazolinones and benzodiazepines, which exhibit antimicrobial, anti-inflammatory, and anticancer properties. Its structure allows for easy functionalization, making it valuable in medicinal chemistry research and drug discovery. Also employed in the preparation of fluorescent dyes and sensors due to its amide and aromatic amine groups that contribute to electron delocalization and light emission properties.
