Description

S-Carbamidomethylcysteine is a chemically modified amino acid derivative, specifically a cysteine derivative where the thiol group is protected by a carbamidomethyl moiety. This compound is of significant value in biochemical research and pharmaceutical development, serving as a key intermediate and building block. It is primarily needed by researchers and manufacturers in the fields of peptide synthesis, proteomics, and the production of specialized biochemical reagents.

Application

• Peptide Synthesis Intermediate: Used as a protected cysteine derivative in solid-phase and solution-phase peptide synthesis to prevent unwanted disulfide bond formation during assembly.
• Bioconjugation & Protein Modification: Acts as a reagent for site-specific modification of proteins and antibodies, enabling the attachment of labels, drugs, or polymers.
• Proteomics Research: Employed in studies involving cysteine alkylation for mass spectrometry analysis and protein sequencing.
• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of more complex active pharmaceutical ingredients (APIs) that contain modified cysteine residues.
• Biochemical Reagent Production: Used in the manufacture of specialized enzymes, inhibitors, and other research-grade biochemicals where a stable, protected thiol group is required.
