Description

1,2,4,6-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference standard is critical for accurate identification, quantification, and toxicological research of persistent organic pollutants (POPs). It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions focused on dioxin and furan analysis.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in environmental and food safety testing.
• Environmental Monitoring: Critical for the analysis and quantification of polychlorinated dibenzofurans (PCDFs) in soil, water, air, and sediment samples to assess contamination levels.
• Food and Feed Safety Analysis: Used in laboratories to screen for and quantify dioxin-like compounds in compliance with strict international food safety regulations (e.g., EU, FDA).
• Toxicological and Biomedical Research: Serves as a precise chemical entity for studying the mechanisms of toxicity, bioaccumulation, and the health impacts of chlorinated furans.
• Quality Control and Method Development: Essential for developing, validating, and verifying analytical methods in accredited testing laboratories.
• Regulatory Compliance and Proficiency Testing: Used in inter-laboratory comparison studies and to ensure analytical methods meet regulatory requirements for POPs monitoring under the Stockholm Convention.
