Cas no 24947-73-7 (Cysteine,N-acetyl-S-methyl-)
N-Acetyl-S-methyl-L-cysteine is a modified cysteine derivative characterized by the acetylation of the amino group and methylation of the thiol group. This structural modification enhances its stability compared to free cysteine, reducing susceptibility to oxidation and degradation. The compound is utilized in biochemical research as a thiol-blocking agent or precursor in peptide synthesis, where controlled reactivity of the sulfur moiety is required. Its acetyl group improves membrane permeability, making it useful in cellular studies. The methylated thiol group offers selective reactivity, enabling applications in protein modification and protection strategies. This derivative is particularly valuable in studies requiring controlled thiol chemistry under physiological conditions.
