Description

p-Cresol-D3 (Methyl-D3) is a deuterium-labeled isotopologue of p-cresol, where three hydrogen atoms on the methyl group are replaced by deuterium (CAS NO 108561-00-8). This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring precise and accurate analytical measurements. It is primarily needed by research laboratories, pharmaceutical companies, and contract research organizations (CROs) engaged in metabolomics, pharmacokinetic studies, and environmental analysis.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis of p-cresol and related metabolites.
• Tracer compound in metabolic pathway and pharmacokinetic (PK/ADME) studies.
• Quantitative reference material in clinical diagnostics and biomarker research.
• Use in environmental monitoring for the precise quantification of phenolic pollutants.
• Essential reagent in the synthesis of other deuterium-labeled complex molecules.
• Quality control and method development in analytical chemistry laboratories.
