Description

cis-Decahydronaphthalene-D18 is a fully deuterated isotopologue of cis-decalin, a saturated bicyclic hydrocarbon. This compound is a high-purity, isotopically labeled standard of critical importance for analytical and research applications where hydrogen background interference must be eliminated. It is primarily utilized by analytical chemists and researchers in the fields of nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) as a solvent or internal standard.

Application

• NMR Spectroscopy Solvent: Used as a deuterated solvent for analyzing compounds soluble in non-polar media, providing a signal-free background in proton NMR.
• Internal Standard for Mass Spectrometry: Serves as a high-purity, isotopically labeled reference standard in quantitative MS analysis for method development and calibration.
• Chemical Reaction Studies: Employed as an inert, deuterated reaction medium or tracer in mechanistic studies and kinetic isotope effect (KIE) experiments.
• Polymer & Material Science Research: Used in the analysis and characterization of polymers, oils, and other hydrophobic materials via spectroscopic techniques.
• Pharmaceutical Research & Development: Facilitates the structural elucidation and quantification of active pharmaceutical ingredients (APIs) and intermediates during R&D.
• Geochemical & Environmental Analysis: Acts as a standard or spike in the analysis of complex hydrocarbon mixtures from environmental or petrochemical samples.
