Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of pyridine-based drugs. Its structure allows for selective bromination and nitro group transformations, making it valuable in creating active pharmaceutical ingredients (APIs) with targeted biological activity. Commonly employed in antitumor and antimicrobial agent research due to its ability to participate in cross-coupling reactions and nucleophilic substitutions. Also utilized in agrochemical synthesis for developing novel pesticides and herbicides. The N-oxide functionality enhances reactivity and selectivity in various catalytic reactions.
