Fmoc-Cys(tBu)-OH

• Catalog Number: ACM67436139
• Product Name: Fmoc-Cys(tBu)-OH
• CAS: 67436-13-9
• Category: Amino Acids
• Description: The side-chain tBu group is stable to TFA and iodine oxidation. Treatment with MeSiCl3/PhSOPh removes t-Bu and cyclizes in one step without scrambling existing disulphide bonds. Removed with Hg(II) to give cysteinyl peptides.
• Synonyms: Fmoc-Cys(tBu)-OH, N-α-Fmoc-S-t.-butyl-L-cysteine
• Molecular Weight: 399.5
