Used primarily in organic synthesis, it serves as a key intermediate for the production of various pharmaceuticals and agrochemicals. Its bromine atoms make it a valuable building block for constructing complex molecules through substitution reactions. In medicinal chemistry, it is employed to develop compounds with potential antibacterial, antifungal, or anticancer properties. Additionally, it finds applications in the synthesis of fluorescent dyes and materials for optoelectronic devices due to its quinoline backbone, which contributes to photophysical properties. Its versatility in cross-coupling reactions also makes it useful in creating advanced materials and catalysts.
