Description

Hexamethylbenzene-D18 is a fully deuterated isotopologue of hexamethylbenzene, where all hydrogen atoms are replaced by deuterium (CAS No. 4342-40-9). This high-purity deuterated standard is critical for applications requiring minimal spectral interference from proton signals, such as in advanced nuclear magnetic resonance (NMR) spectroscopy. It is an essential material for researchers and analytical laboratories in the pharmaceutical, chemical, and academic sectors who require precise internal standards for quantitative analysis and mechanistic studies.

Application

• NMR Spectroscopy Internal Standard: Serves as a primary chemical shift and quantitative reference standard in deuterated solvents for 1H, 13C, and 2H NMR.
• Mechanistic Reaction Studies: Used as a tracer or probe in reaction mechanisms to study kinetics, isotope effects, and molecular rearrangements.
• Mass Spectrometry Calibration: Acts as a high-mass, stable calibration standard for accurate mass measurement in MS and LC-MS systems.
• Deuterium Labeling Reference: Provides a benchmark for the synthesis and analysis of other deuterium-labeled compounds.
• Material Science Research: Employed in the study of organic semiconductors, liquid crystals, and host-guest chemistry where isotopic purity is required.
• Quality Control in Deuterated Solvent Production: Used to assess the purity and isotopic enrichment of commercial deuterated solvents.
