Description

1,2,3,4,7,9-Hexachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) chemical class, identified by CAS NO 91538-84-0. This compound is of critical importance as a certified reference material and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs) such as dioxins and furans in complex matrices.

Application

• Certified Reference Standard for the calibration of GC-MS and HRGC/HRMS systems in environmental analysis.
• Analytical Method Development & Validation for the precise quantification of PCDFs in air, water, soil, and biological samples.
• Toxicological & Ecotoxicological Research to study the environmental fate, bioaccumulation, and health effects of dioxin-like compounds.
• Quality Control/Quality Assurance (QC/QA) in commercial testing laboratories performing compliance analysis for regulations like the Stockholm Convention.
• Forensic Environmental Analysis for source identification and apportionment in contamination incidents.
• Manufacturing of Calibration Solutions & Kits for environmental monitoring equipment and laboratory suppliers.
