Cas no 80745-10-4 (H-Arg(Mtr)-OH H2O)

H-Arg(Mtr)-OH·H?O is a protected derivative of L-arginine, where the guanidine group is shielded by the 4-methoxy-2,3,6-trimethylbenzenesulfonyl (Mtr) protecting group. This compound is widely used in peptide synthesis to prevent unwanted side reactions during coupling steps, ensuring high purity and yield. The Mtr group offers selective deprotection under mild acidic conditions, making it suitable for sensitive peptide sequences. The inclusion of water (H?O) in the formulation enhances stability and handling. Its compatibility with standard solid-phase and solution-phase synthesis protocols makes it a versatile choice for researchers. This reagent is particularly valuable in constructing complex peptides requiring orthogonal protection strategies.
