Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antitumor agents. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for modifying quinoline-based scaffolds to enhance binding affinity and selectivity toward specific biological targets. Also utilized in research settings for generating fluorinated analogs to improve metabolic stability and pharmacokinetic properties of drug candidates.
