Description

1,2,4,6,8-Pentachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) chemical class. This compound is of significant importance as a certified reference material and analytical standard for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs) like dioxins and furans in environmental matrices, industrial emissions, and biological samples.

Application

• Certified Reference Standard for the calibration of analytical instruments (GC-MS, HRGC/HRMS) in dioxin analysis.
• Quality Control Material for method validation and proficiency testing in environmental and food safety laboratories.
• Toxicological Research to study the specific biological activity, metabolism, and health effects of individual PCDF congeners.
• Environmental Forensics for source identification and apportionment in contamination site investigations.
• Regulatory Compliance Testing to monitor industrial processes and emissions against international standards (e.g., Stockholm Convention, EU directives).
