Description

p-Xylene-D10 CAS NO 41051-88-1 is a deuterated isotopologue of para-xylene, where ten hydrogen atoms are replaced with deuterium, serving as a critical internal standard and tracer in analytical chemistry. This high isotopic purity compound is essential for ensuring accuracy and reliability in quantitative nuclear magnetic resonance (qNMR) spectroscopy and mass spectrometry analyses. It is primarily utilized by research institutions, pharmaceutical developers, and chemical manufacturers engaged in advanced material science, metabolic studies, and complex mixture analysis where precise molecular tracking is required.

Application

• Internal Standard for Quantitative NMR (qNMR): Provides a highly stable, non-interfering reference signal for the precise quantification of organic compounds and impurities.
• Mass Spectrometry Tracer: Used in GC-MS and LC-MS methods to track reaction pathways, study metabolic processes, and improve analytical method accuracy.
• Solvent for Spectroscopy: Acts as a deuterated solvent in NMR spectroscopy for analyzing compounds soluble in aromatic solvents, offering minimal background interference.
• Chemical Reaction Studies: Employed in kinetic and mechanistic studies to investigate reaction intermediates and pathways using isotopic labeling techniques.
• Polymer and Material Science Research: Used in the synthesis and analysis of deuterated polymers and advanced materials to study structure-property relationships.
• Pharmaceutical Research & Development: Critical in drug metabolism and pharmacokinetics (DMPK) studies for labeling and tracing active pharmaceutical ingredients (APIs).
