Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to the presence of reactive bromo and ketone functional groups, enabling coupling reactions and further derivatization. Commonly employed in research settings to construct quinoline-based bioactive molecules with potential antitumor and antimicrobial activities. Also utilized in the preparation of fluorescent probes for biochemical assays, leveraging the quinoline scaffold’s inherent photophysical properties.
