Description

2,3,8-Trichlorodibenzofuran CAS NO 57717-32-5 is a specific chlorinated dibenzofuran congener of significant interest in environmental and analytical chemistry. This compound serves as a critical reference standard and research material for the study of polychlorinated dibenzofurans (PCDFs), a class of persistent organic pollutants. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in dioxin analysis, environmental fate studies, and toxicological research to ensure accurate identification and quantification.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring: Used in method development and validation for detecting and quantifying PCDFs in soil, water, air, and biological samples.
• Toxicological Research: Serves as a key compound in studies investigating the formation, environmental behavior, and health effects of chlorinated dioxins and furans.
• Quality Control: Employed as an internal or external standard in laboratory quality assurance/quality control (QA/QC) protocols for compliance with EPA, EU, and other international methods.
• Chemical Synthesis Research: Used as a building block or intermediate in specialized organic synthesis studies focused on halogenated aromatic systems.
• Regulatory Compliance Testing: Essential for laboratories performing testing to meet regulatory limits for dioxins and furans in industrial emissions, food, and feed.
