Description

1,2,3,7,8,9-Hexachlorodibenzo-p-Dioxin is a specific, highly chlorinated congener of the polychlorinated dibenzo-p-dioxin (PCDD) family, a group of compounds of significant environmental and toxicological interest. Its precise chemical structure makes it a critical reference standard and analytical tool for research and regulatory compliance monitoring. This compound is essential for laboratories and industries focused on environmental analysis, toxicology studies, and the development of detection methods for persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HRGC-HRMS in the detection and quantification of dioxins in soil, water, air, and biological samples.
• Toxicological Research: Serves as a precise congener for studying the structure-activity relationships, metabolic pathways, and specific toxic effects (e.g., endocrine disruption, carcinogenicity) of chlorinated dioxins.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods to ensure accuracy, precision, and regulatory compliance (e.g., EPA Method 1613, 8290) in testing laboratories.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike recovery standard to assess the performance and reliability of analytical procedures for dioxin analysis.
• Regulatory Compliance and Monitoring: Used by government agencies and commercial labs to monitor industrial emissions, waste incineration, and food/feed safety in accordance with international treaties like the Stockholm Convention.
• Forensic and Source Identification Studies: Aids in chemical fingerprinting to trace the origin and distribution of dioxin contamination in environmental forensic investigations.
