Description

3,5,6-Trichloro-2-Pyridinol Glucuronide is a key conjugated metabolite of the organophosphate insecticide chlorpyrifos. This compound is critical for environmental monitoring, toxicological research, and regulatory compliance, serving as a definitive biomarker for exposure assessment. It is primarily utilized by analytical laboratories, agrochemical manufacturers, and research institutions focused on pesticide metabolism, human biomonitoring, and ecological safety studies.

Application

• Biomarker Reference Standard: Serves as a certified reference material (CRM) for the accurate quantification of chlorpyrifos exposure in human and animal urine samples for biomonitoring programs.
• Toxicology & Metabolism Studies: Essential for investigating the metabolic pathways, pharmacokinetics, and excretion profiles of chlorpyrifos in preclinical and environmental toxicology research.
• Environmental Analysis: Used as an analytical standard in LC-MS/MS and HPLC methods to detect and quantify pesticide residues in water, soil, and agricultural runoff.
• Regulatory Compliance & Method Development: Supports the development and validation of analytical methods required for regulatory submissions to agencies like the EPA and EFSA.
• Diagnostic Kit Manufacturing: Employed in the production and calibration of immunoassay kits designed for rapid screening of organophosphate pesticide metabolites.
• Academic Research: A vital reagent for universities and research institutes studying the environmental fate and human health impacts of organophosphate pesticides.
