Description

Ethyl-D5-Benzene is a deuterated analog of ethylbenzene, where five hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This high isotopic purity is critical for applications requiring minimal spectral interference or precise mass labeling. It serves as an essential internal standard and tracer in advanced analytical chemistry and materials science research. Key industries utilizing this compound include pharmaceutical development, organic electronics, and nuclear magnetic resonance (NMR) spectroscopy.

Application

• NMR Spectroscopy Solvent & Internal Standard: Used as a deuterated solvent or quantitative internal standard due to its distinct spectral signature, minimizing background interference in proton NMR analysis.
• Mass Spectrometry Tracer: Employed as a stable isotope-labeled internal standard for accurate quantification in GC-MS and LC-MS methods, particularly in metabolomics and pharmacokinetic studies.
• Organic Semiconductor Research: Acts as a deuterated precursor or additive in the synthesis and study of deuterated organic electronic materials to investigate charge transport and stability.
• Mechanistic Reaction Studies: Utilized in kinetic isotope effect (KIE) studies to elucidate reaction mechanisms and pathways in organic synthesis and catalysis.
• Pharmaceutical Impurity Profiling: Serves as a reference standard in the identification and quantification of process-related impurities and degradation products.
• Polymer Science: Used in the synthesis of deuterated polymers for neutron scattering studies to analyze polymer structure, dynamics, and blend morphology.
