Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and antimicrobial agents. Its structure supports the creation of quinoline-based drugs that interfere with pathogen replication. Also employed in research for developing novel bioactive compounds due to its ability to interact with enzymes and receptors in biological systems. Shows potential in agrochemical applications as a building block for plant protection agents. Its chloro and hydroxy functional groups allow for further chemical modifications, making it valuable in medicinal chemistry and drug design.
