Description

2,3,6,7-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener of significant interest in environmental and analytical chemistry. This compound serves as a critical reference standard and analytical tool for the detection and quantification of polychlorinated dibenzofurans (PCDFs), which are persistent environmental pollutants. It is essential for researchers, analytical laboratories, and regulatory bodies involved in environmental monitoring, toxicological studies, and the analysis of complex matrices for dioxin-like compounds.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating analytical instruments like GC-MS and HRGC-HRMS in dioxin analysis.
• Environmental Monitoring: Used in method development and validation for detecting and quantifying PCDFs in soil, water, air, and sediment samples.
• Food and Feed Safety Analysis: Critical for testing compliance with maximum levels of dioxins and dioxin-like PCBs in foodstuffs and animal feed.
• Toxicological Research: Employed in studies to understand the environmental fate, bioaccumulation, and specific toxic effects of chlorinated dibenzofuran congeners.
• Quality Control: Serves as an internal or external standard in laboratory quality assurance/quality control (QA/QC) protocols for dioxin testing.
• Regulatory Compliance: Supports testing to meet international regulations such as EU, US EPA, and JIS methods governing persistent organic pollutants (POPs).
