Z-Dab(Boc)-OH is a protected derivative of diaminobutyric acid (Dab), with the α-amino group protected by Z (benzyloxycarbonyl) and the side-chain amino group by Boc (tert-butyloxycarbonyl). Used in peptide synthesis as a building block for introducing Dab into peptide chains. The protecting groups ensure selective reactions during peptide assembly. Commonly applied in the production of bioactive peptides, peptidomimetics, and drug development. Its stability and compatibility with solid-phase peptide synthesis (SPPS) make it a valuable tool in pharmaceutical research and organic chemistry.
