Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antimalarial drugs. Its structure supports the creation of bioactive molecules due to the presence of reactive sites that can be modified for enhanced pharmacological activity. It is also employed in research settings to design novel quinoline-based agents with potential antimicrobial and anti-inflammatory properties. The chlorine and trifluoromethyl groups contribute to increased lipophilicity and metabolic stability, making it valuable in medicinal chemistry for optimizing drug candidates.
