This compound is widely used in organic synthesis, particularly in peptide chemistry. It serves as a protected intermediate for the introduction of phenylacetic acid derivatives into peptides or other complex molecules. The Boc (tert-butoxycarbonyl) group provides stability during synthetic processes, allowing selective deprotection when needed. It is also employed in the development of pharmaceutical agents, where it acts as a building block for creating bioactive molecules or drug candidates. Additionally, it finds utility in the preparation of chiral compounds, aiding in the synthesis of enantiomerically pure substances for research or industrial applications.
