Description

(Diethyl-D10) 3,5,6-Trichloro-2-Pyridyl Phosph is a deuterated isotopologue of the organophosphorus compound chlorpyrifos, specifically labeled with ten deuterium atoms on the two ethyl groups. This compound is of significant value as a high-purity internal standard for advanced analytical techniques, ensuring precise quantification and method validation in complex matrices. It is primarily required by analytical laboratories, agrochemical manufacturers, and environmental testing facilities engaged in residue analysis, metabolic studies, and regulatory compliance testing.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for accurate quantification via GC-MS or LC-MS/MS in pesticide residue analysis due to its isotopic labeling, which minimizes matrix effects.
• Metabolic and Environmental Fate Studies: Used as a tracer to investigate the degradation pathways, bioaccumulation, and environmental persistence of chlorpyrifos and its metabolites.
• Quality Control & Method Development: Serves as a critical reference material for developing, validating, and auditing analytical methods in compliance with ISO 17025 or GLP standards.
• Forensic and Regulatory Analysis: Supports laboratories in confirming the identity and concentration of chlorpyrifos in food, water, and soil samples for regulatory submissions and safety monitoring.
• Pharmaceutical Impurity Profiling: Potential use in researching and quantifying organophosphorus-related impurities or degradants in pharmaceutical synthesis.
• Stable Isotope Labeled Compound Synthesis: Acts as a building block or precursor for synthesizing more complex deuterated molecules for research.
