Description

1,2,4,6,8,9-Hexachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) chemical class, identified by CAS NO 69698-59-5. This compound is of significant 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 environmental, food, and biological samples.

Application

• Certified Reference Standard for the calibration of analytical instruments (GC-MS, HRGC/HRMS) in dioxin analysis.
• Quality Control and Method Validation in environmental testing laboratories for soil, water, and air pollution studies.
• Toxicological and Ecotoxicological Research to study the fate, transport, and biological effects of chlorinated dibenzofurans.
• Food and Feed Safety Analysis for compliance with international maximum residue limits (MRLs) for dioxin-like compounds.
• Waste and Emission Monitoring from industrial processes to ensure adherence to regulations like the Stockholm Convention on POPs.
• Pharmaceutical Impurity Profiling and safety assessment in certain chemical synthesis pathways.
