Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of agrochemicals and bioactive molecules. Its structure enables selective functionalization, making it valuable in creating complex heterocyclic compounds. Commonly employed in cross-coupling reactions and nucleophilic substitutions due to the activating effect of the N-oxide group. Also utilized in the preparation of trifluoromethyl-substituted pyridine derivatives, which exhibit enhanced metabolic stability and lipophilicity in drug candidates.
