Description

n-Octadecyl-1,1-D2 Alcohol is a deuterium-labeled analog of stearyl alcohol, a long-chain primary fatty alcohol. This compound is specifically designed for use as an internal standard or tracer in advanced analytical and research applications, offering superior precision in mass spectrometry and NMR studies. It is essential for researchers and quality control laboratories in the pharmaceutical, agrochemical, and material science industries who require high-fidelity isotopic labeling for kinetic studies, metabolic pathway tracing, and quantitative analysis.

Application

• Internal Standard for Quantitative Analysis: Used as a deuterated internal standard in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of stearyl alcohol and related compounds.
• Metabolic Tracer: Employed in pharmaceutical and biochemical research to trace metabolic pathways and study the pharmacokinetics of lipid-based compounds.
• NMR Spectroscopy: Serves as a useful probe in Nuclear Magnetic Resonance (NMR) spectroscopy due to the distinct signal of the deuterium atoms, aiding in structural elucidation and mechanistic studies.
• Polymer & Material Science: Acts as a labeled starting material or additive in the synthesis of specialized polymers, surfactants, and lubricants, allowing for the study of material properties and degradation.
• Isotope Dilution Mass Spectrometry (IDMS): A critical component in high-precision IDMS methods for regulatory testing and reference material certification.
