BOC-L-PHE-OME is widely used in peptide synthesis as a protected amino acid derivative. It serves as a crucial building block in the production of peptides, ensuring the selective reactivity of the amino group during coupling reactions. The BOC (tert-butoxycarbonyl) group protects the amino functionality, while the methyl ester (OME) protects the carboxyl group, allowing for controlled stepwise peptide chain assembly. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps achieve high purity and yield of the target peptides. Its stability and ease of deprotection make it a preferred choice in pharmaceutical research and the development of peptide-based drugs. Additionally, it is utilized in the study of peptide structure-activity relationships and in the synthesis of bioactive peptides for therapeutic applications.
