Description

1,3,7,9-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, identified by CAS NO 64560-17-4. This compound is of significant importance as a critical reference standard and analytical standard for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies involved in the detection and study of persistent organic pollutants (POPs) like dioxins and furans.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and quantification of polychlorinated dibenzofurans (PCDFs) in environmental and biological samples via GC-MS or HRGC/HRMS.
• Environmental Analysis: Critical for testing soil, water, sediment, and air samples to assess contamination levels and comply with international regulations on POPs.
• Food and Feed Safety Testing: Used in the analysis of dioxin and furan contamination in food products, animal feed, and edible oils to ensure consumer safety.
• Toxicological Research: Serves as a precise chemical entity in studies investigating the metabolism, environmental fate, and specific toxic effects of chlorinated dibenzofurans.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical methods for the detection of dioxin-like compounds.
• Quality Control in Industrial Processes: Used to monitor and control emissions from waste incineration, metallurgical processes, and chemical manufacturing where PCDFs may be unintentional by-products.
