Description

3,4,6,7-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, identified by CAS NO 57117-40-5. This compound is of significant importance as a critical analytical reference standard and research chemical for environmental and toxicological studies. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers involved in the analysis of persistent organic pollutants (POPs), dioxin-related compounds, 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, food, and biological samples via GC-MS or HRGC/HRMS.
• Environmental Research: Used in studies investigating the environmental distribution, bioaccumulation, and degradation pathways of chlorinated dioxins and furans.
• Toxicological Studies: Serves as a key compound in research to determine the relative toxicity, metabolic pathways, and health impact profiles of specific PCDF congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods for POPs monitoring in compliance with international protocols (e.g., US EPA, EU).
• Quality Control Material: Used as a spike or control material in laboratory proficiency testing and internal quality assurance programs for dioxin analysis.
• Chemical Synthesis Intermediate: May be utilized as a building block or precursor in specialized organic synthesis for research purposes.
