Description

1,2,3,6-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. Its precise structure makes it a critical reference standard and analytical marker for the identification and quantification of polychlorinated dibenzofurans (PCDFs). This high-purity compound is essential for research laboratories, environmental testing facilities, and regulatory bodies engaged in dioxin analysis, toxicological studies, and method development.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring: Used in the quantification of PCDF congeners in soil, water, air, and biological samples to assess contamination levels.
• Toxicological Research: Serves as a pure congener for studying the structure-activity relationships, metabolic pathways, and health effects of chlorinated dioxins and furans.
• Method Development & Validation: Critical for developing, optimizing, and validating analytical methods for persistent organic pollutant (POP) detection according to EPA, EU, and other international standards.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal or recovery standard in laboratory QC protocols to ensure accuracy and precision in analytical results.
• Regulatory Compliance Testing: Essential for laboratories performing compliance testing for industries such as waste incineration, chemical manufacturing, and food safety to meet regulatory limits for dioxins and furans.
