Description

1,2,6,8-Tetrachlorodibenzo-p-Dioxin is a specific chlorinated dioxin congener of significant interest in analytical and environmental chemistry. This compound serves as a critical reference standard for the precise identification and quantification of dioxin and furan contaminants in complex matrices. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in regulatory compliance, toxicological studies, and environmental fate analysis. The availability of a high-purity, well-characterized standard is essential for ensuring the accuracy and reliability of sensitive analytical methods.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating GC-MS and HRGC/HRMS systems in dioxin analysis.
• Environmental Monitoring: Calibration and quality control for testing soil, water, sediment, and air samples for persistent organic pollutant (POP) contamination.
• Food and Feed Safety Analysis: Used in methods to determine dioxin levels in food products, animal feed, and edible oils to ensure compliance with international safety regulations (e.g., EU, FDA).
• Toxicological Research: Serves as a specific congener for studying the structure-activity relationships, metabolic pathways, and environmental persistence of chlorinated dioxins.
• Waste and Emission Testing: Essential for analyzing industrial emissions, incinerator fly ash, and chemical waste to monitor and control dioxin release.
• Method Development and Validation: Used by laboratories to develop, optimize, and validate new analytical protocols for dioxin detection.
• Quality Assurance/Quality Control (QA/QC): Employed as an internal standard or spike recovery standard to assess the accuracy and precision of analytical runs.
• Regulatory Compliance: Supports testing mandated by global regulations such as the Stockholm Convention on POPs, EPA Method 1613, and EU directives.
