Description

2,4,6,7-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran compound, identified by CAS NO 57117-38-1. This compound is of significant interest in analytical chemistry and environmental research, serving as a critical reference standard for the detection and quantification of polychlorinated dibenzofurans (PCDFs). It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in environmental monitoring, food safety, and toxicological studies to ensure accurate calibration and method validation.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for calibrating analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Analysis: Crucial for the detection and quantification of dioxin-like compounds in soil, water, air, and industrial emission samples to comply with global regulations (e.g., Stockholm Convention).
• Food and Feed Safety Testing: Used in laboratories to analyze contaminants in food products, animal feed, and edible oils, ensuring compliance with strict safety limits for persistent organic pollutants (POPs).
• Toxicological Research: Serves as a precise chemical entity in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical methods for the trace-level analysis of PCDFs and related compounds.
• Quality Control in Manufacturing: Used by producers of related chemicals or materials to monitor and control the presence of trace impurities.
