Description

1,2,3,4,6,7,8-Heptachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of compounds of significant environmental and analytical interest. Its precise chemical structure makes it a critical reference standard and analytical standard for accurate identification and quantification in complex matrices. This compound is primarily required by environmental testing laboratories, research institutions, and regulatory bodies involved in monitoring dioxin and furan contamination.

Application

• Primary Use as an Analytical Reference Standard: Calibration and validation of analytical methods (GC-MS, HRGC/HRMS) for dioxin analysis.
• Environmental Monitoring and Forensics: Quantifying PCDF levels in soil, sediment, water, and air samples to assess pollution sources and compliance with international regulations (e.g., Stockholm Convention).
• Food and Feed Safety Analysis: Testing for the presence of persistent organic pollutants (POPs) to ensure food chain safety.
• Toxicological and Ecotoxicological Research: Studying the environmental fate, behavior, and toxic effects of specific dioxin-like compounds.
• Quality Control in Industrial Processes: Monitoring emissions from waste incineration, metallurgical processes, and chemical manufacturing where PCDFs may be unintentional by-products.
• Method Development and Proficiency Testing: Used by laboratories to develop, optimize, and validate new analytical protocols and in inter-laboratory comparison studies.
