Description

1,2,3,4,7,8-Hexachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of compounds of significant environmental and analytical interest. This compound is primarily utilized as a critical reference standard and analytical standard for precise quantification and method validation in environmental monitoring and toxicological research. It is essential for laboratories and research institutions focused on dioxin analysis, environmental forensics, and regulatory compliance testing, where accurate identification and measurement of persistent organic pollutants (POPs) are paramount.

Application

• Primary Use as an Analytical Reference Standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring and Analysis of soil, water, air, and biological samples for polychlorinated dibenzofuran contamination.
• Toxicological and Ecotoxicological Research to study the fate, behavior, and biological effects of specific PCDF congeners.
• Quality Control and Method Development in commercial and regulatory testing laboratories to ensure analytical accuracy and reproducibility.
• Regulatory Compliance and Forensic Analysis for investigating pollution sources and adhering to international treaties like the Stockholm Convention on POPs.
• Certified Reference Material (CRM) production for use in proficiency testing and laboratory accreditation schemes.
