Description

p-Chloro-m-Xylenol-D6 is a deuterated isotopologue of the common antimicrobial agent p-Chloro-m-xylenol (PCMX). This compound is specifically designed for use as an internal standard in analytical chemistry, providing unmatched accuracy for quantitative analysis. It is essential for researchers and quality control laboratories in the pharmaceutical, agrochemical, and environmental sectors who require precise measurement of PCMX levels in complex matrices.

Application

• Primary use as a deuterated internal standard for the accurate quantification of p-Chloro-m-xylenol via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Critical component in method development and validation for regulatory compliance in pharmaceutical impurity profiling and stability studies.
• Used in environmental monitoring to trace and quantify PCMX residues in water and soil samples.
• Essential for dermal absorption and pharmacokinetic studies in cosmetic and topical pharmaceutical research.
• Supports forensic and toxicological analysis where precise identification and measurement of biocides are required.
• Facilitates metabolite studies in biological systems to understand the degradation pathways of PCMX.
