Description

p-Terphenyl-D14 is a deuterated isotopologue of p-terphenyl, where fourteen hydrogen atoms are replaced with deuterium. This high-purity labeled compound is essential for applications requiring minimal spectral interference and enhanced stability in analytical and research settings. It is primarily used by researchers and manufacturers in the fields of analytical chemistry, organic electronics, and materials science for use as an internal standard, a matrix for MALDI-MS, or a building block in advanced materials.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a deuterated internal standard for the accurate quantification of terphenyls and related aromatic compounds via GC-MS or LC-MS, correcting for instrument variability and sample preparation losses.
• Matrix for MALDI-TOF MS: Serves as a high-performance matrix material for Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry, particularly for the analysis of synthetic polymers and large organic molecules.
• NMR Spectroscopy Solvent & Shift Reagent: Employed as a deuterated solvent additive or shift reagent in Nuclear Magnetic Resonance (NMR) spectroscopy to simplify complex spectra.
• Organic Semiconductor Research: Acts as a key precursor or dopant in the research and development of organic light-emitting diodes (OLEDs) and other electronic devices due to its stable aromatic structure.
• Scintillator & Phosphor Development: Investigated for use in the synthesis of novel scintillation materials and phosphors for radiation detection and lighting applications.
• Chemical Synthesis Intermediate: Utilized as a specialized, labeled building block in synthetic organic chemistry for creating deuterated complex molecules for mechanistic studies.
