QUICK LINKS

Z-Trp(Boc)-OH (dicyclohexylammonium) salt is a protected amino acid derivative in peptide synthesis. The Z-group, a carbobenzoxy protecting group, shields the amino functionality, while the Boc group, a tert-butoxycarbonyl moiety, protects the indole side chain of the tryptophan residue. This dual protection strategy when constructing peptides with precise sequences, as it prevents side reactions during the coupling stages. It′s this specificity that makes the compound a staple in solid-phase peptide synthesis protocols. The dicyclohexylammonium counterion aids in the solubility of the compound in organic solvents, which is beneficial for different synthesis techniques.
