Description

1,2,3,4,7-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, regulatory bodies, and research institutions focused on dioxin analysis, environmental fate studies, and compliance testing for persistent organic pollutants (POPs).

Application

• Certified Reference Standard for the calibration of analytical instruments (GC-MS, HRGC/HRMS) in dioxin analysis.
• Environmental Monitoring and testing for POPs in soil, water, sediment, and air samples as per international protocols.
• Toxicological Research to study the biological effects, metabolism, and congener-specific toxicity of PCDFs.
• Quality Control in laboratories to validate analytical methods and ensure accuracy in congener-specific reporting.
• Regulatory Compliance Testing for products and materials to meet global restrictions on dioxin and furan content.
• Forensic Analysis to identify sources of contamination in environmental incident investigations.
