Used as an intermediate in the synthesis of pharmaceuticals, particularly in antimalarial, antimicrobial, and antiviral drugs. It serves as a building block in medicinal chemistry due to its quinoline core, which is known for biological activity, with derivatives showing potential as antibacterial agents. Also employed in the development of agrochemicals and dyes. Additionally, used as a reagent in organic synthesis reactions, such as transition metal-catalyzed carbon-carbon bond formation. It finds applications in materials science for creating fluorescent compounds or coordination compounds with special properties for chemical sensors. Its chloro and methyl substituents enhance reactivity for further functionalization in organic synthesis.
