Description

1,2,3,8-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, identified by CAS NO 62615-08-1. This compound is of significant importance as a critical reference standard and analytical reagent for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies involved in the detection and study of persistent organic pollutants (POPs), particularly dioxins and furans.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and validation of analytical instruments like GC-MS and HRGC/HRMS in dioxin analysis.
• Environmental Testing: Essential for quantifying and monitoring trace levels of polychlorinated dibenzofurans (PCDFs) in soil, water, air, and sediment samples to assess contamination.
• Toxicological Research: Used in scientific studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual chlorinated dibenzofuran congeners.
• Food and Feed Safety Analysis: Employed in laboratories to ensure compliance with stringent international regulations regarding dioxin and furan limits in the food chain.
• Method Development and Proficiency Testing: Critical for developing new analytical methods and for use in inter-laboratory comparison tests to ensure accuracy and reproducibility.
• Waste and Emission Control: Used to analyze industrial emissions and waste incineration by-products for regulatory compliance and environmental impact assessments.
