Description

2,4,6,8-Tetrachlorodibenzofuran CAS NO 58802-19-0 is a chlorinated dibenzofuran compound of significant interest in environmental and analytical chemistry. It serves as a critical reference standard and analytical tool for the detection and quantification of persistent organic pollutants. This high-purity material is essential for researchers and quality control laboratories in environmental monitoring, regulatory compliance, and toxicological studies.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating equipment and validating analytical methods in the detection of dioxin-like compounds.
• Toxicological Research: Used in scientific studies to investigate the environmental fate, bioaccumulation, and toxic effects of polychlorinated dibenzofurans (PCDFs).
• Regulatory Compliance Testing: Essential for laboratories performing analysis to comply with international regulations (e.g., Stockholm Convention, EPA methods) governing persistent organic pollutants (POPs).
• Food and Feed Safety: Employed in the analysis of dioxin and furan contamination levels in food, animal feed, and related products to ensure public health safety.
• Waste and Emission Monitoring: Applied in the analysis of industrial emissions, incinerator fly ash, and contaminated soils and sediments.
• Method Development and Validation: Serves as a key component in the development and accreditation of new high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) methods.
• Quality Assurance/Quality Control (QA/QC): Used as an internal standard or spike in analytical procedures to ensure accuracy, precision, and recovery rates.
