Used as a key intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It participates in cycloaddition reactions to form nitrogen-containing rings, which are common structures in pharmaceuticals and agrochemicals. Its reactivity with electrophiles and nucleophiles makes it valuable for constructing complex molecules, especially in the development of bioactive agents. Commonly employed in the synthesis of cyanopyridines and related derivatives, which have applications in medicinal chemistry and materials science.
