Used as an intermediate in the synthesis of fluoroquinolone antibiotics, particularly in the development of potent antimicrobial agents. Its structure allows for further functionalization at the quinoline core, enabling the production of compounds with enhanced biological activity against Gram-positive and Gram-negative bacteria. Commonly employed in pharmaceutical research to build more complex molecules with improved pharmacokinetic properties. Also utilized in the preparation of kinase inhibitors and other bioactive heterocycles in medicinal chemistry.
