BOC-PHE-GLY-OME is widely used in peptide synthesis as a protected intermediate. It serves as a building block for constructing larger peptide chains, ensuring specific amino acids are incorporated at desired positions. The BOC (tert-butyloxycarbonyl) group protects the amine functionality during synthesis, preventing unwanted reactions, while the methyl ester (OME) protects the carboxyl group. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase synthesis, enabling the production of peptides with high precision and purity. Its applications extend to the development of pharmaceuticals, bioactive peptides, and research tools for studying protein interactions and functions.
