Boc-Arg(NO2)-OH（Cat No.:I043019）is a protected derivative of the amino acid arginine, where the N-terminal amine group is protected by a tert-butoxycarbonyl (Boc) group, and the guanidine side chain of arginine is modified with a nitro group (NO₂). This compound is commonly used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), to incorporate arginine with specific modifications. The Boc group allows for controlled deprotection during synthesis, while the nitro group can influence the peptide’s biological activity, making it useful in studies of enzyme inhibition, receptor binding, and other bioactive applications.
