N-α-Z-N-ε-tosyl-L-lysine dicyclohexylamine salt is a protected lysine derivative featuring an Nα-benzyloxycarbonyl (Z/Cbz-type) carbamate at the α-amino group and an Nε-tosyl (tosylsulfonamide) protecting group on the ε-amino group, with the lysine backbone retaining a free carboxyl group. The molecule is present as a dicyclohexylamine salt, and its side chain contains the protected ε-nitrogen while the α-amino functionality is masked by the Z group, yielding a zwitterionic salt-forming profile driven by the carboxylate. This salt-form, along with the dual N-protection pattern, is used as a peptide-building block in peptide synthesis workflows where controlled chemoselectivity is required for stepwise assembly and for minimizing side reactions associated with unprotected amines.
