Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antitubercular and antibacterial agents. Its structure allows for selective substitutions, making it valuable in constructing nitrogen-containing heterocyclic compounds. Commonly employed in the preparation of pyridine-based drug candidates due to its reactivity toward nucleophilic displacement, especially at the 3-chloro position. Also utilized in agrochemical research for developing novel pesticides and herbicides where pyridine derivatives exhibit biological activity.
