| Fmoc-Cys(Trt)-OH | Fmoc-Cys(Trt)-OH is a cysteine derivative [1]. Uses: Scientific research. Group: Peptides. CAS No. 103213-32-7. Pack Sizes: 100 g; 500 g. Product ID: HY-W007798. |  |
| 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. Ideally, this derivative should be introduced using the symmetrical anhydride or DIPCDI/HOBt activation to minimize enantiomerization. If activation with uronium or phosphonium reagents, such as HBTU or PyBOP, is to be employed, it is strongly recommended that collidine is used as the base , as this has been shown to significantly reduce loss of optical integrity during coupling. Uses: Peptide synthesis. Additional or Alternative Names: Fmoc-Cys(Trt)-OH, N-α-Fmoc-S-trityl-L-cysteine. Product Category: Amino Acids. CAS No. 103213-32-7. Molecular formula: C37H31NO4S. Mole weight: 585.71. Product ID: ACM103213327-1. Alfa Chemistry ISO 9001:2015 Certified. |  |
