Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block for synthesizing bioactive molecules due to the presence of both ester and amine functional groups, which allow for further chemical modifications. Commonly employed in the preparation of central nervous system agents and receptor ligands. Its benzylamino and butanoate structure makes it suitable for creating analogs in medicinal chemistry research, especially in studies related to neurotransmitter modulation.
