Description

Dodecyl-D25 Sulfate, Sodium Salt is a fully deuterated analog of sodium dodecyl sulfate (SDS), where all hydrogen atoms in the dodecyl chain are replaced with deuterium. This compound is critical for advanced research applications where isotopic labeling is required to eliminate background interference and enable precise structural analysis. It is primarily utilized by scientists and manufacturers in the fields of analytical chemistry, structural biology, and materials science for specialized spectroscopic and scattering techniques.

Application

• As a deuterated surfactant in Small-Angle Neutron Scattering (SANS) studies for investigating micelle and membrane structures.
• As a critical component in Nuclear Magnetic Resonance (NMR) spectroscopy for sample preparation and alignment media, leveraging its isotopic purity.
• For use in Fourier-Transform Infrared (FTIR) and Raman spectroscopy as a matrix or standard where a deuterated background is essential.
• In the preparation of deuterated model systems for biophysical research on protein-lipid interactions and membrane dynamics.
• As a specialty surfactant in the formulation of advanced materials where isotopic contrast is needed for characterization.
• For analytical method development and as an internal standard in mass spectrometry.
