CAS 177582-21-7: Fmoc-Cys(Mmt)-OH

Description: Fmoc-Cys(Mmt)-OH, also known as Fmoc-protected cysteine with a methoxytrityl (Mmt) protecting group, is a chemical compound commonly used in peptide synthesis. It features a phenylmethoxycarbonyl (Fmoc) group, which serves as a protective group for the amino group of cysteine, allowing for selective reactions during peptide assembly. The Mmt group protects the thiol side chain of cysteine, preventing unwanted reactions while facilitating the synthesis of peptides that contain this amino acid. This compound is typically utilized in solid-phase peptide synthesis (SPPS) due to its stability and compatibility with various coupling reagents. Fmoc-Cys(Mmt)-OH is characterized by its ability to undergo deprotection under mild acidic conditions, releasing the free cysteine residue for further reactions. The presence of both Fmoc and Mmt groups allows for greater control over the synthesis process, making it a valuable intermediate in the production of peptides and proteins for research and therapeutic applications. Its CAS number, 177582-21-7, is a unique identifier that aids in the cataloging and retrieval of information related to this specific compound.
