Used in organic synthesis as a key intermediate for the development of various pharmaceuticals, particularly in the creation of compounds with potential anti-inflammatory, antimicrobial, and anticancer properties. It serves as a building block in the synthesis of complex molecules, aiding in the study of structure-activity relationships in drug discovery. Additionally, it is utilized in the preparation of fluorescent dyes and probes for biological imaging and diagnostics due to its quinoline core, which exhibits desirable photophysical properties.
