Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and other bioactive compounds. Acts as a versatile building block in organic synthesis due to its ability to undergo selective substitution reactions. Employed in the preparation of agrochemicals, including herbicides and fungicides, where it contributes to the development of more effective and selective crop protection agents. Also utilized in the formation of ligands for catalytic processes, enhancing reaction efficiency in metal-catalyzed transformations. Its N-oxide functionality facilitates ring-opening and rearrangement reactions, making it valuable in heterocyclic chemistry research.
