Fmoc-Cys(Trt)-OH
High purity Fmoc-protected amino acid for research and process production of peptides, with very low levels of dipeptide, free-amino acids and acetic acid impurities. The standard derivative for Fmoc SPPS of peptides containing Cys. The Trt group is removed with 95% TFA containing 1-5% TIS.
