Description

1,4,6,8-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference material is essential for accurate calibration, method validation, and toxicological research. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis and regulatory compliance.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantitative analysis of polychlorinated dibenzofurans (PCDFs) via GC-MS or HRGC/HRMS.
• Environmental Monitoring: Calibration and quality control in testing for dioxin-like compounds in soil, water, air, and waste samples to meet EPA and international guidelines.
• Food and Feed Safety: Used in the analysis of contaminants to ensure compliance with strict EU and global limits for dioxins and PCBs/PCDFs in the food chain.
• Toxicological Studies: Serves as a precise congener in research investigating the specific biological activity, metabolism, and health effects of chlorinated dibenzofurans.
• Method Development & Validation: Critical for developing, optimizing, and validating analytical methods in accordance with standards like US EPA Method 1613 and 8290.
• Quality Assurance/Quality Control (QA/QC): Implementation in laboratory proficiency testing and as an internal or recovery standard in complex matrices.
