This compound is primarily utilized in peptide synthesis, where it serves as a protected form of the amino acid D-homoserine. The Boc (tert-butoxycarbonyl) group acts as a protective shield for the amino group during the peptide chain assembly, preventing unwanted reactions. It is particularly useful in solid-phase peptide synthesis (SPPS) and solution-phase methods, ensuring the selective formation of peptide bonds. After the synthesis is complete, the Boc group can be easily removed under acidic conditions, revealing the free amino group for further modifications or final peptide assembly. Its application is crucial in the production of custom peptides for research, pharmaceuticals, and biotechnology.
