Tos-L-Arg-NH2*HCl is a protected L-arginine derivative in which the amino acid side chain retains the guanidinium functionality while the alpha-amino group is present as an amide-forming amino acid amine (L-Arg-NH2) and the tosyl (Ts) group provides N-protection. The molecule is supplied as a hydrochloride salt, pairing the basic sites to form a stable ionic form and supporting handling in peptide and amine chemistry, with the tosyl substituent controlling chemoselectivity by reducing undesired nucleophilicity at the protected nitrogen. In synthesis and chemical biology workflows, this compound is used as a building block or intermediate for preparing arginine-containing peptides and peptide-like amides, as well as for generating further arginine derivatives where controlled deprotection and subsequent coupling steps depend on the presence of the tosyl-protected amino functionality.
