Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor agonists and other bioactive compounds. Its structure, featuring chloro, nitro, and carboxylic acid groups on a pyridine core, allows for selective functionalization such as nucleophilic substitution at the chloro position and reduction of the nitro group to amino, making it valuable in creating derivatives with potential neurological activity. Also employed in agrochemical research for developing new pesticides due to its electron-withdrawing groups and heterocyclic core. Commonly utilized in medicinal chemistry for scaffold modification in drug discovery programs targeting central nervous system disorders.
