Description

n-Acetyl-S-(2-Hydroxyethyl)Cysteine is a chemically modified derivative of the amino acid cysteine, featuring an acetylated amine group and a hydroxyethylated thiol side chain. This modification enhances its stability and alters its reactivity profile, making it a valuable biochemical building block and research tool. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and life science sectors for applications ranging from drug discovery to biochemical synthesis.

Application

• Biochemical Research & Proteomics: Used as a model compound or reagent in studies of protein structure, thiol chemistry, and post-translational modifications.
• Pharmaceutical Intermediates: Serves as a key synthetic precursor or building block in the development of novel therapeutic agents, particularly those targeting oxidative stress or requiring specific thiol reactivity.
• Antioxidant Studies: Employed in research to investigate antioxidant mechanisms and the role of modified cysteine derivatives in cellular redox balance.
• Chelating Agent Synthesis: Acts as a starting material for the synthesis of specialized chelating ligands due to its thiol and hydroxyl functional groups.
• Reference Standard: Used as a high-purity analytical standard in HPLC, LC-MS, or NMR for method development and quality control in related chemical processes.
• Cosmetic & Personal Care Ingredients: Potential use in the formulation of advanced skincare products for its modified, potentially more stable, antioxidant properties.
