Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds. It participates in cycloaddition reactions to form pyrimidine and triazine derivatives, which are important in the development of pharmaceuticals and agrochemicals. Its nitrile and ester functionalities allow for versatile reactivity, making it valuable in constructing nitrogen-containing rings. Also employed in the synthesis of functional materials and dyes due to its electron-withdrawing groups and ability to undergo nucleophilic transformations.
