Description

1,2,3,4,6,9-Hexachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, identified by CAS NO 91538-83-9. This compound is of significant importance as a critical analytical reference standard and research chemical for environmental and toxicological studies. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the analysis of persistent organic pollutants (POPs), dioxins, and furans.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and quantification of polychlorinated dibenzofurans (PCDFs) in environmental and biological samples via GC-MS or HRGC/HRMS.
• Environmental Monitoring: Used in method development and quality control for analyzing soil, water, sediment, and air samples to assess contamination levels of dioxin-like compounds.
• Toxicological Research: Serves as a precise congener in studies investigating the structure-activity relationships, metabolic pathways, and toxic effects (e.g., endocrine disruption, carcinogenicity) of chlorinated dibenzofurans.
• Food and Feed Safety Analysis: Employed as a calibration standard in laboratories testing for dioxin and furan contamination in food chains, ensuring compliance with strict international safety regulations (e.g., EU, FDA).
• Waste and Emission Testing: Critical for the analysis of industrial emissions, incineration fly ash, and other waste streams to monitor and control the release of hazardous pollutants.
• Regulatory Compliance and Proficiency Testing: Used by accredited labs to validate analytical methods and participate in inter-laboratory comparison studies to meet regulatory requirements for POPs monitoring under the Stockholm Convention.
