Description

m-Cresol-D7 is a deuterated isotopologue of m-cresol, where seven hydrogen atoms are replaced by deuterium, serving as a critical internal standard and tracer in advanced analytical chemistry. This high-purity labeled compound is essential for ensuring accuracy and reliability in quantitative analyses, particularly in complex matrices. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental sectors for applications requiring precise measurement and metabolic pathway elucidation.

Application

• Internal Standard for Quantitative Analysis: Used in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of m-cresol and related phenolic compounds.
• Metabolic and Pharmacokinetic Studies: Acts as a stable isotopic tracer to investigate the absorption, distribution, metabolism, and excretion (ADME) of cresols in biological systems.
• Environmental Fate and Tracing: Employed in research to track the degradation, transformation, and movement of phenolic pollutants in environmental samples.
• NMR Spectroscopy Solvent & Reagent: Useful as a deuterated solvent or reagent in Nuclear Magnetic Resonance (NMR) spectroscopy due to its isotopic purity.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities and degradants in active pharmaceutical ingredient (API) development.
• Chemical Reaction Mechanism Studies: Serves as a probe in mechanistic studies to understand reaction pathways involving methylphenol derivatives.
