Description

1,2,3,6,7,8-Hexachlorodibenzo-p-Dioxin is a specific, highly chlorinated congener of the polychlorinated dibenzo-p-dioxin (PCDD) family. This compound is of significant interest in environmental analysis and toxicological research due to its structural relationship to more potent dioxins. It serves as a critical analytical reference standard and research chemical for scientists and laboratories worldwide. Primary users include environmental testing facilities, regulatory bodies, and academic institutions focused on persistent organic pollutant (POP) analysis, method development, and fate/transport studies.

Application

• Analytical Reference Standard: Used for the calibration of GC-MS and HRGC/HRMS systems in the quantification of dioxin and furan congeners in environmental and biological samples.
• Environmental Monitoring: Serves as a critical component in method validation and quality assurance/quality control (QA/QC) protocols for analyzing soil, water, sediment, and air samples for POP contamination.
• Toxicological Research: Employed in laboratory studies to investigate the comparative toxicity, biochemical pathways, and health effects of different dioxin congeners.
• Regulatory Compliance Testing: Essential for laboratories performing analysis to comply with international regulations such as the Stockholm Convention, EPA Method 1613, and EU directives on dioxins in food and feed.
• Method Development: Used by researchers to develop and optimize new analytical techniques for the separation, identification, and detection of complex halogenated aromatic compounds.
• Forensic Chemistry: Can be utilized as a marker or comparative standard in forensic investigations related to chemical fingerprinting of pollution sources.
