BOC-Ile-Gly-OH is primarily used in peptide synthesis as a building block for creating more complex peptide structures. It serves as a protected dipeptide, where the BOC (tert-butoxycarbonyl) group safeguards the amino group during the synthesis process. This compound is particularly useful in solid-phase peptide synthesis (SPPS), enabling the stepwise assembly of peptides with high precision. Its application extends to the development of pharmaceuticals, where it contributes to the production of peptide-based drugs, including those targeting metabolic disorders, cancer, and infectious diseases. Additionally, it is employed in research settings to study peptide interactions, folding, and biological activity, aiding in the discovery of novel therapeutic agents.
