Description

1,2,3,6,7-Pentachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of compounds of significant environmental and analytical interest. This compound is primarily utilized as a critical reference standard and analytical standard for precise identification and quantification in complex matrices. It is essential for laboratories and research institutions focused on environmental monitoring, toxicological studies, and regulatory compliance testing for persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis: Quantification of PCDFs in soil, sediment, water, and air samples for pollution assessment and site remediation studies.
• Food and Feed Safety Testing: Detection and measurement of dioxin-like compounds in compliance with strict EU and global food safety regulations.
• Toxicological Research: Used in studies to understand the congener-specific toxicity, bioaccumulation, and metabolic pathways of chlorinated dibenzofurans.
• Quality Control & Method Validation: Serves as a spike or recovery standard in laboratory QC procedures to validate analytical methods for dioxin analysis.
• Regulatory Compliance: Essential for testing industrial emissions, incineration outputs, and chemical products to meet standards set by the Stockholm Convention, EPA, and other regulatory bodies.
