Used as an intermediate in the synthesis of quinolone-based pharmaceuticals, particularly in the development of antibacterial and antiviral agents. Its structure supports the construction of complex heterocyclic systems important in medicinal chemistry. Commonly employed in research settings to design kinase inhibitors and other bioactive molecules due to the bromo and ester functionalities that allow for further chemical modifications. Also utilized in the preparation of fluorescent probes and dyes owing to its conjugated aromatic core.
