Description

Hexadecyltrimethylammonium Bromide-D9 is a deuterated analog of the widely used cationic surfactant, cetyltrimethylammonium bromide (CTAB), where nine hydrogen atoms are replaced by deuterium. This isotopic labeling is critical for advanced analytical and research applications where molecular tracing, structural elucidation, or non-interfering spectroscopic studies are required. It is an essential material for researchers and developers in the pharmaceutical, life sciences, and advanced materials sectors who require high-fidelity isotopic standards for mass spectrometry, NMR spectroscopy, and mechanistic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a quantitative and qualitative reference standard in LC-MS and GC-MS analysis of surfactants and related compounds, leveraging its distinct mass shift.
• NMR Spectroscopy Studies: Used as a deuterated probe in nuclear magnetic resonance to investigate molecular structures, dynamics, and interactions without signal interference from protonated species.
• Mechanistic & Metabolic Tracing: Enables precise tracking of surfactant pathways in chemical, biological, and environmental systems for research in drug metabolism, environmental fate, and reaction mechanisms.
• Surface Science & Materials Research: Utilized in the study of micelle formation, self-assembly processes, and interfacial phenomena where isotopic labeling is necessary to distinguish components.
• Pharmaceutical R&D: Supports formulation development and analytical method validation for products containing quaternary ammonium compounds.
• Specialty Chemical Synthesis: Acts as a labeled building block or catalyst template in the synthesis of more complex deuterated compounds.

Quality Control

Our Hexadecyltrimethylammonium Bromide-D9 is manufactured under strict quality systems to ensure high isotopic purity and chemical integrity, suitable for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-content), chemical purity, and identity confirmation. We adhere to relevant standards for research chemicals, and custom synthesis and purification to meet specific project requirements is available upon request.

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 after each use to prevent absorption of atmospheric moisture, which can affect stability and purity.
