Description

Hexadecyltrimethylammonium Bromide-D33 is a deuterated cationic surfactant, specifically a perdeuterated isotopologue of the common quaternary ammonium compound cetyltrimethylammonium bromide (CTAB). This compound is essential for advanced research and analytical applications where isotopic labeling is required to eliminate background interference or to study molecular mechanisms using techniques like NMR spectroscopy. It is primarily needed by research institutions, pharmaceutical developers, and specialty chemical manufacturers working in deuterium labeling, surface chemistry studies, and as a critical standard in mass spectrometry.

Application

• NMR Spectroscopy: Used as an internal standard or a deuterated surfactant template for structural analysis and dynamics studies in solution.
• Mass Spectrometry & Analytical Standards: Serves as a high-purity isotopic standard for quantitative analysis and method development.
• Surface Science & Colloid Chemistry Research: Employed in studies of micelle formation, interfacial behavior, and self-assembly processes without proton interference.
• Deuterium-Labeled Compound Synthesis: Acts as a key precursor or building block for synthesizing more complex deuterated materials.
• Pharmaceutical R&D: Utilized in metabolic pathway tracing and pharmacokinetic studies using stable isotopes.
• Polymer & Material Science: Used in the preparation and study of deuterated polymers and nanocomposites for neutron scattering experiments.

Quality Control

Our Hexadecyltrimethylammonium Bromide-D33 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high isotopic purity and chemical identity, meeting the stringent requirements for research-grade deuterated compounds. Certificates of Analysis (COA) detailing isotopic enrichment (D-atom %), chemical purity, and analytical methods (NMR, HPLC, MS) are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after opening to prevent degradation from moisture absorption.
