Description

1,2,3,4,6,7,8-Heptachlorodibenzo-p-Dioxin is a specific, high-purity chlorinated dioxin congener, essential for analytical and research purposes. This compound is a critical reference standard for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis: Calibration and quantification in the analysis of soil, water, sediment, and air samples for dioxin contamination.
• Food and Feed Safety Testing: Used in methods to determine dioxin levels in foodstuffs, animal feed, and edible oils to ensure regulatory compliance.
• Toxicological Research: Serves as a precise congener in studies investigating the metabolism, toxicity, and environmental fate of polychlorinated dibenzo-p-dioxins (PCDDs).
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for dioxin detection.
• Quality Control/Quality Assurance (QC/QA): Used as a spike or control standard in laboratory proficiency testing and internal quality assurance programs.
• Regulatory Compliance and Monitoring: Supports compliance with international regulations such as the Stockholm Convention on POPs, EU directives, and US EPA methods.
