Boc-Cys(pMeOBzl)-OH (CAS: 18942-46-6) is a cystine derivative, used in various chemical synthesis and peptide chemistry. Boc-Cys(pMeOBzl)-OH, Amino acids and derivatives, peptide synthesis, organic synthesis intermediate, pharmaceutical intermediates, biochemical reagents. Boc-Cys(pMeOBzl)-OH is one of the cysteine derivatives commonly utilized in Boc SPPS. The 4-methoxybenzyl group is removed by HF or TFMSA during cleavage of the peptide from the resin. The cysteine sidechain is released as a free sulfhydryl group. Disulfide bonds can be formed later by a variety of oxidation methods.
