Boc-D-Lys(Boc)-OH DCHA (CAS 204190-67-0) is the dicyclohexylammonium salt of Nα,Nε-di-Boc-protected D-lysine. Both the α-amino and ε-amino groups of the D-lysine residue are Boc-protected, while DCHA is present as the salt component.
This protected D-lysine derivative is useful where D-lysine stereochemistry and temporary protection of both amino groups are required during synthesis. The specified DCHA salt form should be considered when comparing molecular weight, stoichiometry, solubility, and lot-specific analytical data.

Protection and Salt Form
The D-lysine component retains the normal lysine side-chain framework with D stereochemistry. Its α-amino and ε-amino groups are both Boc-protected, while dicyclohexylamine is present as the salt component. DCHA should therefore not be interpreted as a cycloalkyl substituent or structural feature of the lysine residue itself.
Route Compatibility
Evaluate coupling conditions and Boc deprotection requirements in the context of the complete synthetic route. Because both amino groups are Boc-protected, confirm that the planned deprotection sequence is compatible with other acid-sensitive groups and intermediates.
Browse the unusual residue building blocks for related structures. Complex sequence work can also use specialty peptide building blocks.
