Description

1,2,3,4,6,7-Hexachlorodibenzo-p-Dioxin is a specific, high-purity chlorinated dioxin congener, identified by CAS NO 58200-66-1, used primarily as a critical analytical reference standard. This compound is essential for environmental monitoring, toxicological research, and regulatory compliance testing due to its role as a model compound for dioxin analysis. It is a vital material for analytical laboratories, research institutions, and environmental agencies focused on persistent organic pollutant (POP) detection and risk assessment.

Application

• Analytical Reference Standard: Primary use for the calibration of GC-MS and HRGC/HRMS systems in environmental and food testing laboratories.
• Toxicological Research: Serves as a specific congener for studying the structure-activity relationships, metabolism, and biological impact of chlorinated dioxins.
• Method Development & Validation: Critical for developing and validating analytical methods according to EPA, EU, and other international standards for dioxin analysis.
• Quality Control & Assurance: Used in laboratory proficiency testing and as an internal standard to ensure accuracy and precision in complex sample matrices.
• Environmental Monitoring: Applied in the analysis of soil, sediment, water, and air samples to assess contamination levels and track pollutant sources.
• Regulatory Compliance Testing: Essential for testing products, emissions, and waste to ensure adherence to strict global regulations like the Stockholm Convention on POPs.
