Pmc-S-methylisothiourea is a protected amino acid derivative featuring an isothiourea functionality attached through sulfur, with the side-chain sulfur converted to a methyl-substituted isothiourea (S-methylisothiourea) motif. The molecule bears the amino and carboxyl functional groups of an amino acid framework while the side-chain is masked as a Pmc-protected sulfur-containing group (Pmc), which controls chemoselectivity by suppressing undesired sulfur reactivity during peptide-coupling and other stepwise transformations. In synthesis, it is employed as a side-chain-functionalized building block or intermediate for preparing peptides and related conjugates that require an isothiourea-derived handle for subsequent chemical modification or downstream crosslinking-style derivatization under controlled conditions.
