This compound is primarily used in peptide synthesis as a protecting group for amino acids. The Boc (tert-butyloxycarbonyl) group protects the amine functionality, while the Fmoc (fluorenylmethyloxycarbonyl) group can be selectively removed, allowing for stepwise peptide chain elongation. It is particularly useful in solid-phase peptide synthesis (SPPS) where selective deprotection is crucial. The Dab (2,4-diaminobutyric acid) moiety introduces an additional amino group, enabling the incorporation of specific functional groups or branching points in the peptide structure. This makes it valuable in the development of complex peptides, peptidomimetics, and bioconjugates for pharmaceutical research and drug development. Its applications also extend to the synthesis of peptide-based materials and probes for biochemical studies.
