Description

p-Terphenyl-D14 is a deuterated isotopologue of p-terphenyl, where fourteen hydrogen atoms are replaced with deuterium, a stable hydrogen isotope. This high level of deuteration makes it an essential internal standard and tracer in advanced analytical chemistry, particularly for mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It is a critical material for researchers and quality control laboratories in the pharmaceutical, agrochemical, and material science industries who require precise quantification and mechanistic studies without isotopic interference.

Application

• Internal Standard for LC-MS (Liquid Chromatography-Mass Spectrometry) and GC-MS (Gas Chromatography-Mass Spectrometry) analysis of terphenyls and related aromatic compounds.
• Deuterated Tracer in metabolic pathway studies and pharmacokinetic research within drug discovery and development.
• NMR Spectroscopy Solvent and Shift Reference for analyzing complex organic molecules and polymers.
• Chemical Intermediate in the synthesis of deuterated liquid crystals and advanced organic electronic materials.
• Component in scintillation cocktails and radiation detection research.
• Isotope Dilution Analysis for achieving high-precision quantification in environmental and forensic analysis.
