Description

n-Octadecane-D38 is a deuterated analog of octadecane, where all 38 hydrogen atoms are replaced with the stable isotope deuterium. This high isotopic purity makes it an essential internal standard and tracer in advanced analytical chemistry and metabolic research. It is primarily utilized by research scientists and quality control laboratories in the pharmaceutical, environmental, and petrochemical industries for precise quantification and mechanistic studies using techniques like mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of hydrocarbons and similar compounds.
• Metabolic Pathway Tracing: Serves as a stable, non-radioactive isotopic tracer in biological and pharmacological research to study lipid metabolism and drug disposition.
• NMR Spectroscopy Solvent & Reference: Employed as a deuterated solvent or chemical shift reference in nuclear magnetic resonance experiments.
• Petroleum & Fuel Analysis: Acts as a calibration standard in the characterization of complex hydrocarbon mixtures in the petrochemical industry.
• Environmental Science: Used in the analysis and tracing of environmental pollutants and hydrocarbons.
• Polymer Science Research: Utilized in studies of polymerization mechanisms and polymer structure analysis.
• Deuterium Labeling Studies: Provides a source of deuterium atoms for the synthesis of other labeled compounds in research and development.
