Used primarily as a pharmaceutical intermediate in the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of prodrugs and drug delivery systems. Its structure supports enhanced absorption across biological membranes, making it valuable in oral peptide delivery research. It has been investigated for use in improving the bioavailability of poorly absorbed drugs by promoting permeation through the intestinal lining. Additionally, it serves as a building block in the preparation of compounds targeting central nervous system disorders and metabolic diseases. Its ester and amino functional groups allow for versatile chemical modifications in medicinal chemistry workflows.
