Fmoc-Cys(Me)-OH

Description:

Fmoc-Cys(Me)-OH, also known as Fmoc-protected cysteine with a methyl group, is a derivative of the amino acid cysteine. It features a 9-fluorenylmethoxycarbonyl (Fmoc) protecting group, which is commonly used in peptide synthesis to protect the amino group of the amino acid. The presence of a methyl group on the sulfur atom of cysteine (indicated by "Cys(Me)") enhances its stability and alters its reactivity. This compound is typically used in the synthesis of peptides and proteins, particularly in solid-phase peptide synthesis, where the Fmoc group can be easily removed under basic conditions. Fmoc-Cys(Me)-OH is characterized by its ability to form disulfide bonds, which are crucial for the structural integrity of many proteins. Additionally, it exhibits properties typical of thiol-containing compounds, such as nucleophilicity and the ability to participate in redox reactions. Its CAS number, 138021-87-1, allows for precise identification in chemical databases and literature.
