Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for versatile functionalization, making it valuable in constructing complex molecules. The cyano and ester groups enable further transformations such as hydrolysis, reduction, and cyclization reactions. Commonly employed in the synthesis of active ingredients in herbicides and insecticides due to its ability to introduce specific alkyl and functionalized side chains. Also utilized in research for developing novel heterocyclic compounds with potential biological activity.
