Description

2,3,4-Trichlorodibenzofuran CAS NO 57717-34-7 is a specific chlorinated dibenzofuran congener, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference standard is critical for research, method development, and quality control in laboratories worldwide. It is primarily utilized by analytical chemists, environmental scientists, and regulatory bodies for the accurate identification and quantification of polychlorinated dibenzofurans (PCDFs) in complex matrices.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis: Critical for testing and monitoring environmental samples (soil, water, air, sediment) for dioxin and furan contamination as part of regulatory compliance.
• Food and Feed Safety: Used in the analysis of foodstuffs, animal feed, and biological tissues to ensure compliance with strict international safety limits for persistent organic pollutants (POPs).
• Toxicological Research: Serves as a precise congener in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods according to EPA, EU, and other international standards.
• Quality Assurance/Quality Control (QA/QC): Used as an internal standard or spike in laboratory QA/QC protocols to ensure accuracy and precision of analytical results.
• Industrial Emission Testing: Applied in the analysis of stack gases and industrial waste to monitor and control emissions from incineration and chemical processes.
