This chemical is widely used in peptide synthesis, particularly as a protected arginine derivative. It serves as a key building block in the production of peptides, ensuring the arginine residue is shielded during the synthesis process. The Boc (tert-butyloxycarbonyl) group protects the amino group, while the Mts (mesitylene-2-sulfonyl) group safeguards the guanidine function of arginine. This protection is crucial for preventing unwanted side reactions during peptide chain assembly. Additionally, the cyclohexylamine (CHA) salt form enhances its stability and solubility, making it easier to handle in laboratory settings. It is commonly employed in solid-phase peptide synthesis (SPPS) and is valued for its efficiency in creating complex peptide structures, especially in pharmaceutical research and drug development.
