Description

1,2,3,7,8,9-Hcdf is a specific congener of hexachlorodibenzofuran, a polychlorinated dibenzofuran (PCDF) compound identified by CAS NO 72918-21-9. This high-purity reference standard is critical for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the analysis of persistent organic pollutants (POPs) like dioxins and furans.

Application

• Analytical Reference Standard: Primary use as a certified standard for the precise calibration and quantification of PCDFs in environmental and biological samples via HRGC/HRMS.
• Environmental Monitoring: Essential for testing soil, sediment, water, and air samples to assess contamination levels and comply with international regulations (e.g., Stockholm Convention).
• Food and Feed Safety Analysis: Used in the determination of dioxin and furan contamination levels in food chains, ensuring product safety and regulatory adherence.
• Toxicological and Biomedical Research: Serves as a key reagent in studies investigating the metabolism, toxicity, and health effects of specific dioxin-like compounds.
• Quality Control and Method Development: Employed by testing laboratories to validate analytical methods, perform proficiency testing, and ensure the accuracy of results.
• Waste and Emission Testing: Critical for analyzing industrial emissions, incineration fly ash, and other waste streams for hazardous pollutant profiling.
