Used as a key intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the production of advanced pharmaceutical agents with enhanced antimicrobial activity. Its structure supports the formation of core quinolone frameworks, improving drug potency and bioavailability. Also employed in research for developing new central nervous system agents due to its ability to cross the blood-brain barrier. Commonly found in routes for creating kinase inhibitors and other bioactive molecules in medicinal chemistry.
