Fmoc-D-Lys(Boc)-OH, bearing the CAS number 92122-45-7, is a fundamental building block in the intricate world of peptide synthesis. As a derivative of D-lysine, it plays a pivotal role in constructing peptides with specific structural and functional characteristics, particularly those requiring the incorporation of D-amino acids. Understanding its chemical properties is key for R&D scientists and procurement managers seeking to buy this high-value intermediate.

Chemically, Fmoc-D-Lys(Boc)-OH is characterized by its molecular formula C26H32N2O6 and a molecular weight of approximately 468.54 g/mol. The presence of the Fmoc protecting group on the alpha-amino terminus of the D-lysine residue is central to its utility in solid-phase peptide synthesis (SPPS). This group is readily cleaved under mild basic conditions, typically using piperidine, allowing for the controlled elongation of the peptide chain. Concurrently, the Boc protecting group on the epsilon-amino side chain provides robust protection against unwanted reactions during the synthesis process.

The orthogonal nature of the Fmoc and Boc protecting groups is a significant advantage. It allows for selective deprotection and subsequent functionalization or modification at the lysine side chain, a feature highly valued in the synthesis of complex peptides, peptidomimetics, and bioconjugates. Researchers often look to buy Fmoc-D-Lys(Boc)-OH from reputable manufacturers to ensure this chemical precision is maintained throughout their synthesis protocols.

The applications of Fmoc-D-Lys(Boc)-OH are diverse and span multiple areas of chemical and biological research. In pharmaceutical development, it is used to synthesize peptide hormones, enzyme inhibitors, and antimicrobial peptides, where the inclusion of D-amino acids can impart resistance to proteolysis and improve pharmacokinetic profiles.
