Fmoc-Lys(Boc)-OH (Cat No.: R026089) is a protected form of the amino acid lysine, commonly used in solid-phase peptide synthesis (SPPS). It features an Fmoc (9-fluorenylmethyloxycarbonyl) group protecting the α-amino group and a Boc (tert-butoxycarbonyl) group protecting the ε-amino side chain. This dual protection allows selective deprotection and incorporation into peptide chains with precise control over functional group reactivity. Fmoc-Lys(Boc)-OH is essential in synthesizing peptides, proteins, and peptidomimetics, particularly when preserving lysine’s side-chain integrity during assembly.
