Description

p-Toluic-D7 Acid CAS NO 1219798-76-1 is a deuterium-labeled isotopologue of p-toluic acid, where seven hydrogen atoms are replaced by deuterium, serving as a critical internal standard for quantitative mass spectrometry. This high-purity compound is essential for ensuring analytical accuracy and reproducibility in method development and validation. It is primarily utilized by research scientists and quality control laboratories in the pharmaceutical, agrochemical, and environmental testing industries where precise quantification of p-toluic acid or related metabolites is required.

Application

• Internal Standard for LC-MS/MS and GC-MS: Used for the accurate quantification of p-toluic acid in complex biological and environmental matrices.
• Pharmaceutical Metabolism Studies: Employed in pharmacokinetic and drug metabolism research to track and quantify drug metabolites.
• Environmental Analysis: Applied as a tracer or standard in the analysis of water, soil, and industrial waste for toluic acid derivatives.
• Agrochemical Research: Utilized in studies investigating the degradation pathways and environmental fate of herbicides and pesticides.
• Chemical Synthesis: Acts as a deuterated building block for the synthesis of more complex labeled compounds for research.
• Forensic Toxicology: Serves as a reference standard in forensic analyses for substance identification and quantification.
