Used in peptide synthesis as a protected intermediate, particularly in the preparation of complex peptides where the pyroglutamic acid residue is required at the N-terminus. The Boc (tert-butoxycarbonyl) group provides temporary protection of the alpha-amino function, while the dicyclohexylammonium salt enhances crystallinity and solubility in organic solvents, facilitating purification and handling. Commonly employed in solid-phase and solution-phase peptide coupling strategies. Also useful in the synthesis of pharmaceuticals and bioactive peptides that contain pyroglutamate, such as gonadotropin-releasing hormone (GnRH) analogs and other regulatory peptides.
