Description

1,4,6,7-Tetrachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran compound, identified by CAS NO 66794-59-0. This chemical is of significant interest as a reference standard and analytical reagent for environmental and toxicological research. It is primarily required by research institutions, analytical laboratories, and chemical manufacturers engaged in the study of persistent organic pollutants (POPs), dioxin-like compounds, and environmental fate analysis.

Application

• Analytical Reference Standard: Used as a certified standard in gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) for the quantification and identification of polychlorinated dibenzofurans (PCDFs) in environmental samples.
• Toxicological Research: Serves as a key compound in studies investigating the toxicity, bioaccumulation, and metabolic pathways of dioxin-like chemicals.
• Environmental Monitoring: Employed in method development and quality control for analyzing PCDF contaminants in soil, water, air, and biological tissues to comply with global POPs monitoring protocols.
• Chemical Synthesis Intermediate: Acts as a building block or precursor in specialized organic synthesis for developing novel compounds or for degradation studies.
• Regulatory Compliance Testing: Utilized by commercial testing laboratories to calibrate equipment and validate analytical methods for client samples requiring dioxin/furan analysis.
• Academic Research: Fundamental research tool in chemistry and environmental science departments for studying the properties and reactions of halogenated aromatic compounds.
