Description

1,3,6,8-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, a compound class of significant interest in environmental and analytical chemistry. Its precise chemical structure makes it a critical reference standard and analytical standard for the detection and quantification of polychlorinated dibenzofurans (PCDFs) in complex matrices. This product is essential for research laboratories, environmental testing facilities, and regulatory bodies engaged in dioxin analysis, method development, and quality control programs.

Application

• Environmental Analysis: Primary use as a certified reference material (CRM) or analytical standard for the quantification of PCDFs in soil, water, air, and biological samples.
• Food Safety Testing: Calibration standard in the analysis of dioxin and furan contaminants in food and feedstuffs to ensure regulatory compliance.
• Toxicological Research: Used in studies investigating the environmental fate, bioaccumulation, and toxicological profiles of specific chlorinated dibenzofuran congeners.
• Method Development & Validation: Critical component for developing, optimizing, and validating analytical methods such as HRGC/HRMS (High-Resolution Gas Chromatography/High-Resolution Mass Spectrometry).
• Quality Assurance/Quality Control (QA/QC): Serves as a spike or internal standard in laboratory QA/QC protocols to ensure accuracy and precision in dioxin testing.
• Waste and Emission Monitoring: Used in the analysis of industrial emissions, incinerator fly ash, and other waste streams for regulatory monitoring.
