Description

1,3,4,7-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, a compound of significant interest in analytical and environmental chemistry. Its primary value lies in its use as a certified reference material and analytical standard for precise quantification and method validation. This product is essential for laboratories and research institutions focused on environmental monitoring, toxicology studies, and regulatory compliance testing, particularly for the analysis of dioxin-like compounds.

Application

• Certified Reference Standard: For the calibration of analytical instruments (GC-MS, HRGC/HRMS) in environmental and food testing laboratories.
• Environmental Analysis: Used as a critical standard for detecting and quantifying polychlorinated dibenzofurans (PCDFs) in soil, water, air, and sediment samples.
• Toxicological Research: Serves as a precise reagent in studies investigating the biochemical mechanisms, persistence, and health effects of dioxin-like compounds.
• Quality Control & Method Development: Essential for developing, validating, and ensuring the accuracy of analytical methods according to EPA, EU, and other international standards.
• Regulatory Compliance Testing: Supports testing for compliance with global regulations (e.g., Stockholm Convention, REACH) concerning persistent organic pollutants (POPs).
• Forensic and Industrial Investigation: Aids in source identification and fingerprinting in cases of accidental release or contamination events involving chlorinated aromatics.
