Description

1,6,7-Trichlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran compound, identified by CAS NO 83704-46-5. This chemical is a critical reference standard and research intermediate for environmental analysis and toxicological studies, particularly concerning dioxin-like compounds. It is primarily required by analytical laboratories, regulatory agencies, and research institutions focused on persistent organic pollutant (POP) detection, method development, and environmental fate studies.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and quantification of polychlorinated dibenzofurans (PCDFs) in environmental and biological samples via GC-MS or HRGC/HRMS.
• Environmental Research: Studying the environmental distribution, bioaccumulation, and degradation pathways of chlorinated dioxins and furans.
• Toxicological Studies: Investigating the specific toxicity profile, mechanism of action, and structure-activity relationships (SAR) of individual PCDF congeners.
• Method Development & Validation: Used in laboratories to develop, optimize, and validate analytical methods for POPs monitoring in compliance with international protocols (e.g., EPA Method 1613, 8290).
• Quality Control Material: Serves as a spike or recovery check standard in laboratory quality assurance/quality control (QA/QC) programs for dioxin analysis.
• Regulatory Compliance Testing: Essential for testing industrial emissions, waste, food, and feed to ensure compliance with regulations like the Stockholm Convention on POPs.
