This compound is primarily utilized in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected cysteine derivative, where the Fmoc group protects the amino group, and the Pam group protects the thiol side chain of cysteine. This protection ensures selective reactivity during peptide chain assembly, preventing unwanted side reactions. The compound is especially valuable in constructing peptides with disulfide bonds, which are crucial for the structure and function of many biologically active peptides and proteins. Its application is common in the development of therapeutic peptides, research peptides, and in the study of protein folding and interactions.
