N-[(9H-Fluoren-9-ylmethoxy)carbonyl]-S-[(4-methylphenyl)diphenylmethyl]-D-cysteine

Description:
N-[(9H-Fluoren-9-ylmethoxy)carbonyl]-S-[(4-methylphenyl)diphenylmethyl]-D-cysteine, commonly referred to as Fmoc-D-Cys(4-MePh)-OH, is a synthetic amino acid derivative primarily used in peptide synthesis. This compound features a fluorenylmethoxycarbonyl (Fmoc) protecting group, which is widely utilized for the protection of amino groups during solid-phase peptide synthesis. The presence of the sulfur atom in the cysteine moiety allows for the formation of disulfide bonds, which are crucial for the stability and functionality of peptides and proteins. The additional diphenylmethyl and 4-methylphenyl groups enhance the compound's hydrophobic characteristics, influencing its solubility and interaction with other molecules. This compound is typically characterized by its molecular weight, melting point, and spectral data, including NMR and mass spectrometry, which confirm its structure and purity. Its applications extend to the development of peptide-based therapeutics and research in biochemistry and molecular biology, particularly in studies involving protein folding and interactions.
