Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block in the development of antimalarial drugs due to its structural similarity to quinoline-based antimalarials like chloroquine. Also employed in the synthesis of fluorescent dyes and sensors, taking advantage of its photophysical properties. Its derivatives are explored in medicinal chemistry for their potential antimicrobial, anti-inflammatory, and anticancer activities. Additionally, it finds use in coordination chemistry as a ligand for metal ions in catalytic applications.
