Description

1-Bromo-2,3,7,8-Tetrachlorodibenzofuran is a halogenated dibenzofuran derivative, a compound of significant interest in environmental and analytical chemistry. It serves as a critical reference standard and analytical standard for the detection and quantification of polychlorinated dibenzofurans (PCDFs), which are persistent environmental pollutants. This high-purity compound is essential for researchers, analytical laboratories, and regulatory bodies involved in environmental monitoring, toxicology studies, and the development of analytical methods for dioxin-like compounds.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating equipment and validating methods in the analysis of PCDFs in soil, water, air, and biological samples.
• Toxicological Research: Used in scientific studies to investigate the environmental fate, bioaccumulation, and toxicological profiles of brominated/chlorinated dibenzofurans.
• Method Development and Validation: Critical for developing and confirming the accuracy of advanced analytical techniques such as High-Resolution Gas Chromatography/Mass Spectrometry (HRGC/HRMS).
• Quality Control and Assurance: Employed in laboratory QC protocols to ensure the precision and reliability of analytical data for regulatory compliance reporting.
• Dioxin and Furan Congener Analysis: Specifically used for the identification and quantification of this particular congener in complex matrices, supporting POPs (Persistent Organic Pollutants) monitoring programs.
