This chemical is widely used in peptide synthesis, particularly in the protection of arginine residues during the process. It serves as a key intermediate in the production of complex peptides, ensuring the selective deprotection of functional groups. The Mtr (4-methoxy-2,3,6-trimethylbenzenesulfonyl) group provides stability under acidic conditions, making it suitable for solid-phase peptide synthesis. Additionally, its use in combinatorial chemistry and drug development allows for the creation of peptide-based pharmaceuticals with enhanced specificity and efficacy. The cyclohexylamine (CHA) salt form improves solubility and handling, facilitating its application in laboratory and industrial settings.
