Description

1,2,8,9-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference material is essential for accurate identification, quantification, and toxicological study of persistent organic pollutants (POPs). It serves as a critical standard for researchers, regulatory bodies, and testing laboratories engaged in environmental monitoring, food safety analysis, and industrial effluent control, where precise measurement of dioxin-like compounds is paramount.

Application

• Analytical Reference Standard: Primary use as a certified standard for gas chromatography-mass spectrometry (GC-MS) and high-resolution GC-MS (HRGC-MS) in environmental and food testing.
• Environmental Monitoring: Calibration and quality control for the analysis of soil, sediment, air, and water samples to assess contamination levels of polychlorinated dibenzofurans (PCDFs).
• Food and Feed Safety Analysis: Used in laboratories to quantify and monitor PCDF residues in food products, animal feed, and edible oils to ensure compliance with international safety regulations.
• Toxicological Research: Serves as a pure congener for studying the structure-activity relationships, metabolic pathways, and health effects of chlorinated dibenzofurans.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods for dioxin and furan analysis in complex matrices.
• Regulatory Compliance Testing: Essential for laboratories performing compliance testing for regulations such as the Stockholm Convention, EU directives, and EPA methods.
• Waste and Emission Control: Analysis of industrial waste, fly ash, and flue gas emissions from incineration and industrial processes.
• Forensic and Source Identification: Aiding in the chemical fingerprinting of pollution sources by providing a specific congener profile.
