Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the creation of complex quinoline-based compounds that exhibit biological activity. Commonly employed in research settings to build more complex molecules through substitution reactions at the chlorine site. Also utilized in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry. Shows utility in agrochemical research for developing novel pesticides with improved efficacy.
