Description

1,2,4,7,8-Pentachlorodibenzo-p-Dioxin is a specific, high-purity congener of polychlorinated dibenzo-p-dioxins (PCDDs), a class of persistent organic pollutants. This compound is of critical importance for analytical and research purposes, serving as a certified reference material for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on dioxin analysis, risk assessment, and method development.

Application

• Certified Reference Standard (CRM) for the calibration of analytical instruments such as High-Resolution Gas Chromatography/Mass Spectrometry (HRGC/HRMS).
• Environmental Analysis for the precise quantification and monitoring of dioxin contamination in soil, water, air, and sediment samples.
• Food and Feed Safety Testing to ensure compliance with stringent international regulations regarding dioxin levels.
• Toxicological and Biomedical Research to study the mechanisms of action, bioaccumulation, and health effects of specific dioxin congeners.
• Quality Assurance/Quality Control (QA/QC) programs in laboratories to validate analytical methods and ensure data accuracy.
• Regulatory Compliance and Proficiency Testing for laboratories requiring certified materials to meet standards set by agencies like the EPA and EU.
