Used as a key intermediate in the synthesis of pharmaceuticals and biologically active compounds, particularly in the development of serotonin reuptake inhibitors and related central nervous system agents. Its structure supports conjugation and derivatization for use in medicinal chemistry, enabling the formation of cyanoacrylate derivatives with potential anti-inflammatory and neuroactive properties. Also employed in research settings for building complex heterocyclic systems due to its reactive cyano and carboxylic acid functional groups.
