Description

1,4,7,8-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran compound, identified by CAS NO 83704-29-4. This chemical is of significant interest as a critical reference standard and analytical reagent for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs), particularly dioxin-like compounds.

Application

• Environmental Analysis Reference Standard: Serves as a certified calibration standard for the precise quantification of polychlorinated dibenzofurans (PCDFs) in air, water, soil, and sediment samples via GC-MS or HRGC/HRMS.
• Toxicological Research: Used in scientific studies to investigate the biochemical pathways, toxicity profiles, and environmental fate of dioxin-like compounds.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods in compliance with protocols from the EPA, EU, and other international environmental agencies.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike in laboratory QC procedures to ensure accuracy and precision in congener-specific analysis.
• Regulatory Compliance Testing: Used by commercial testing laboratories to screen industrial emissions, waste incineration outputs, and consumer products for regulatory compliance (e.g., Stockholm Convention, REACH).
• Food and Feed Safety: Applied in the analysis of food and animal feed for the presence of PCDF contaminants to ensure public health safety.
