Description

2,3,7,8-Tetrachlorodibenzofuran is a highly chlorinated dibenzofuran congener, a compound of significant interest in environmental and analytical chemistry. It serves as a critical reference standard and analytical standard for the detection and quantification of persistent organic pollutants (POPs). This compound is essential for researchers, regulatory bodies, and testing laboratories involved in environmental monitoring, food safety, and toxicological studies. Its precise characterization is vital for ensuring the accuracy of analyses related to dioxin and furan contamination.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating equipment and validating methods in the analysis of soil, water, and air samples for polychlorinated dibenzofurans (PCDFs).
• Food and Feed Safety Testing: Used as an analytical standard in laboratories to monitor and ensure compliance with maximum residue levels (MRLs) for dioxin-like compounds in foodstuffs, animal feed, and edible oils.
• Toxicological and Biomedical Research: Employed in studies investigating the mechanisms of toxicity, bioaccumulation, and the health impacts of dioxin-like compounds on biological systems.
• Regulatory Compliance and Method Development: Essential for developing, accrediting, and verifying analytical methods (e.g., EPA Method 1613, 8290) to meet global regulatory requirements from agencies like the EPA, EU, and WHO.
• Waste and Emission Monitoring: Applied in the analysis of industrial emissions, incinerator fly ash, and chemical waste to assess and control environmental release of hazardous substances.
• Quality Control in Chemical Manufacturing: Serves as a purity standard for the quality assurance of other chemical products and processes where chlorinated aromatic compounds are involved.
