Used as an intermediate in organic synthesis, particularly in the preparation of nitrogen-containing heterocyclic compounds. It serves as a building block in the development of pharmaceuticals and agrochemicals due to its ability to undergo cycloaddition and nucleophilic addition reactions. Its imine functionality allows for selective transformations, making it valuable in the synthesis of chiral amines and ligands for catalysis. Also employed in research settings for the design of novel sulfonamide-based bioactive molecules.
