Used as a key intermediate in the synthesis of nootropic drugs, particularly in the production of racetam-family cognitive enhancers. Its structure, featuring a benzonitrile moiety and a 3-bromo-2-oxopyrrolidin-1-yl substituent, supports the development of compounds that influence neurotransmitter activity in the brain, especially those targeting memory improvement and neuroprotection. The bromine atom and other reactive functional groups allow for further chemical modifications, making it valuable in pharmaceutical research and development. It is also employed in the preparation of biologically active molecules for studying central nervous system disorders.
