Trt-D-Dap(Fmoc)-OH is a protected, non-proteinogenic amino acid derivative featuring a D-configured diaminopropyl (Dap) side chain bearing two amino functionalities, with the α-amino acid framework and a carboxylic acid group. The side-chain amino groups are protected by a trityl (Trt) group, while the α-amino functionality is protected as an Fmoc carbamate, providing orthogonal protection that suppresses undesired amine reactivity during stepwise peptide assembly. As a protected amino acid building block, it is used to introduce a Dap residue into peptide synthesis or peptide-related intermediates, supporting controlled chemoselectivity for subsequent deprotection and coupling steps.
