N-(Dodecyl-d25)-N,N-dimethyl-3-ammonio-1-propanesulphonate

N-(Dodecyl-d25)-N,N-dimethyl-3-ammonio-1-propanesulphonate, also known as D25-SDS, is a deuterated form of the anionic detergent sodium dodecyl sulfate (SDS). It is commonly used in biochemistry and molecular biology research as a protein denaturant and surfactant in various applications including electrophoresis, chromatography, and protein solubilization. D25-SDS has a molecular weight of 341.6 g/mol and a chemical formula of C16H35D25NO4S. It is a zwitterionic surfactant, meaning it contains both positively and negatively charged groups, which allows it to interact with both hydrophobic and hydrophilic molecules. This property makes it a powerful tool for solubilizing and denaturing proteins for further analysis. In addition to its surfactant properties, D25-SDS can also act as a chiral agent in NMR spectroscopy due to the presence of deuterium atoms in the dodecyl chain. This makes it useful in studying the structure and dynamics of biomolecules. While D25-SDS is generally considered safe for use in research settings, it should be handled with care as it can cause skin and eye irritation. It is also important to properly dispose of any waste containing D25-SDS as it can have negative impacts on the environment.
