Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with antimicrobial and antiviral properties. It serves as a building block in the preparation of substituted pyridine derivatives, which are common structural motifs in drug design. Its nitro and chloro functional groups allow for selective transformations, enabling coupling reactions and nucleophilic substitutions in multi-step organic syntheses. Commonly employed in research and development for agrochemicals and medicinal chemistry due to its reactivity and ability to form complex heterocyclic systems.
