Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for drugs targeting central nervous system disorders. Its strained cyclobutane ring enhances reactivity, making it valuable in constructing complex organic molecules. Also employed in agrochemicals for creating novel pesticides with improved efficacy. The nitrile and carboxylic acid functional groups allow for diverse chemical modifications, enabling its use in peptide mimetics and heterocyclic compound synthesis.
