Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It serves as a building block for quinolinone-based drugs that exhibit potential anticonvulsant, anxiolytic, and neuroprotective activities. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for optimizing drug candidates targeting neurological disorders. Additionally, it has been explored in the design of kinase inhibitors and antimicrobial agents due to its favorable binding properties with biological targets.
