Description

n-Hexadecyltrimethylammonium-D42 Bromide is a deuterated analog of the common cationic surfactant cetyltrimethylammonium bromide (CTAB), where all hydrogen atoms on the alkyl chain are replaced by deuterium. This high-purity isotopically labeled compound is critical for advanced research applications requiring precise molecular tracking and analysis. It is primarily utilized by researchers and scientists in the fields of analytical chemistry, materials science, and life sciences for applications such as NMR spectroscopy and mechanistic studies.

Application

• As an internal standard or reference material in quantitative Nuclear Magnetic Resonance (qNMR) spectroscopy.
• For mechanistic studies in surface chemistry and catalysis, where deuterium labeling allows for detailed reaction pathway analysis.
• In the preparation of deuterated micelles or vesicles for biophysical research and membrane protein studies.
• As a templating agent in the synthesis of nanostructured materials, where its isotopic purity can influence material properties.
• For use in mass spectrometry (MS) as a labeled standard to improve accuracy in quantitative analysis.
• In fundamental research on surfactant behavior and self-assembly using techniques like Small-Angle Neutron Scattering (SANS).
