Description

1,3,6,7-Tetrachlorodibenzofuran is a specific chlorinated dibenzofuran congener, a compound of significant interest in environmental and analytical chemistry. It serves as a critical reference standard and analytical standard for the identification and quantification of polychlorinated dibenzofurans (PCDFs), which are persistent environmental pollutants. This high-purity material is essential for research laboratories, environmental testing facilities, and regulatory bodies engaged in dioxin analysis, method development, and quality control programs.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring: Used in the analysis of soil, sediment, water, and air samples to assess contamination levels of PCDFs.
• Food and Feed Safety Testing: Critical for compliance testing to ensure levels of dioxin-like compounds are within regulatory limits (e.g., EU, FDA).
• Toxicological Research: Employed in studies investigating the environmental fate, bioaccumulation, and toxic effects of specific dioxin congeners.
• Method Development and Validation: Serves as a key component in developing and validating new analytical methods for persistent organic pollutants (POPs).
• Quality Assurance/Quality Control (QA/QC): Used as an internal or external standard to ensure the accuracy and precision of analytical data in commercial and government labs.
