Description

Mesityl-D10 Oxide, 98 Atom % D is a deuterated derivative of mesityl oxide, featuring ten deuterium atoms (D) at the aromatic methyl positions with a high isotopic enrichment of 98 atom %. This high level of deuteration makes it an invaluable internal standard and tracer in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy, ensuring analytical accuracy by eliminating signal interference from protonated species. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and advanced materials sectors for method development, metabolic studies, and precise impurity profiling.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical, non-interfering reference compound for the accurate quantification of mesityl oxide and related metabolites in complex biological and environmental matrices.
• NMR Spectroscopy Solvent & Tracer: Used as a deuterated solvent shift reagent or as a tracer in reaction mechanism studies to track the fate of methyl groups via 2H-NMR.
• Pharmaceutical Research & Metabolism Studies: Enables precise pharmacokinetic and metabolic pathway analysis of drug candidates in preclinical development.
• Polymer & Materials Science: Acts as a deuterated monomer or additive in the synthesis of labeled polymers for studying molecular dynamics, diffusion, and structure-property relationships.
• Environmental Analysis: Employed as a surrogate standard in the GC-MS or LC-MS analysis of volatile organic compounds (VOCs) and solvent residues.
• Chemical Synthesis Intermediate: Provides a deuterated building block for the synthesis of more complex labeled compounds for research purposes.
