Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure supports the development of compounds with biological activity, particularly in herbicides and antimicrobial agents. Commonly employed in research settings for the preparation of quinoline-based derivatives that exhibit potential therapeutic properties. Also utilized in the manufacturing of dyes and pigments due to its aromatic and electron-rich framework. Its chlorinated and methylated features enhance reactivity in coupling reactions, making it valuable in organic synthesis and medicinal chemistry.
