Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. It serves as a building block in the development of active ingredients due to its reactive chlorine and electron-deficient pyridine ring, which facilitate substitution reactions. Commonly employed in the manufacture of pyridine-based crop protection agents, enhancing efficacy against weeds and plant pathogens. Also utilized in research for developing novel bioactive compounds with potential antimicrobial or insecticidal properties.
