Description

1,2,3,7,9-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, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and environmental agencies involved in the detection and quantification of persistent organic pollutants (POPs) like dioxins and furans in complex matrices.

Application

• Certified Reference Standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Analytical Method Development and Validation for the accurate identification and quantification of PCDFs in environmental samples.
• Quality Control (QC) and Proficiency Testing in commercial and regulatory laboratories to ensure analytical data integrity.
• Toxicological and Environmental Fate Studies to understand the behavior, bioaccumulation, and specific congener toxicity of chlorinated dibenzofurans.
• Regulatory Compliance Testing for monitoring emissions and contamination levels as per international treaties like the Stockholm Convention.
• Research on Formation Mechanisms in thermal processes to support pollution prevention and control strategies.
