Description

1,3,4,6,8-Pentachlorodibenzofuran is a high-purity, specialized chlorinated dibenzofuran compound, identified by CAS NO 83704-55-6. This chemical is of significant importance as a critical reference standard and analytical reagent for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs), specifically dioxin-like compounds.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating analytical instruments like HRGC/HRMS in dioxin and furan testing of air, water, soil, and sediment samples.
• Toxicological Research: Serves as a key analyte in studies investigating the environmental fate, bioaccumulation, and toxic effects of polychlorinated dibenzofurans (PCDFs).
• Food and Feed Safety Testing: Used as an analytical standard in compliance testing to monitor and control dioxin contamination levels in the food chain, ensuring regulatory adherence.
• Waste and Emission Monitoring: Essential for analyzing industrial emissions, incineration flue gases, and chemical waste to assess compliance with international conventions like the Stockholm Convention on POPs.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods for the precise separation and identification of specific PCDF congeners.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and internal quality control programs to ensure accuracy and reliability of analytical data.
