Used primarily in the development of antimalarial drugs, this compound serves as a key intermediate in synthesizing medications effective against Plasmodium species, especially in targeting the dormant liver stages of P. vivax and P. ovale. Its quinoline structure supports the creation of derivatives that improve tissue penetration and prolong drug action, making it valuable in radical cure therapies. Additionally, it has shown potential in antimicrobial research, as an antioxidant, and as a scaffold in medicinal chemistry for designing novel bioactive molecules. It is also studied in coordination chemistry due to its ability to act as a ligand for transition metals, potentially applicable in sensors or catalysts.
