Description

1,2,7,8-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener of significant interest in environmental and analytical chemistry. Its precise structure makes it a critical reference standard for the analysis of polychlorinated dibenzofurans (PCDFs), a class of persistent organic pollutants. This high-purity compound is essential for researchers, regulatory bodies, and testing laboratories engaged in environmental monitoring, food safety, and toxicological studies to ensure accurate identification and quantification.

Application

• Environmental Analysis Reference Standard: Primary use as an analytical standard for the detection and quantification of PCDFs in soil, water, and air samples.
• Food and Feed Safety Testing: Calibrating instruments for monitoring dioxin and furan contamination levels in the food chain to comply with global safety regulations.
• Toxicological Research: Serving as a pure congener for studying the specific biological effects, metabolic pathways, and toxicity profiles of chlorinated dibenzofurans.
• Waste and Emission Monitoring: Used in methods to analyze industrial emissions and waste incineration byproducts for regulatory compliance (e.g., EPA, EU directives).
• Quality Control and Method Validation: Essential for developing, validating, and ensuring the accuracy of analytical methods (GC-MS, HRGC/HRMS) in certified testing laboratories.
• Calibration and System Suitability: Used to calibrate high-resolution mass spectrometers and confirm the performance of chromatographic systems for congener-specific analysis.
