Description

1,2,3,4,8,9-Hexachlorodibenzofuran CAS NO 92341-07-6 is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of persistent organic pollutants. This compound is of critical importance as a certified reference material and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of dioxin-like compounds in complex matrices such as soil, water, air, and biological tissues.

Application

• Certified Reference Standard for the calibration of high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) systems in dioxin analysis.
• Analytical Method Development and Validation for the precise identification and quantification of PCDFs in environmental and food safety testing.
• Toxicological and Ecotoxicological Research to study the congener-specific behavior, bioaccumulation, and health effects of dioxin-like compounds.
• Quality Control/Quality Assurance (QC/QA) in commercial testing laboratories to ensure accuracy and reliability of analytical results.
• Regulatory Compliance Testing supporting protocols for EPA, EU, and other international regulations concerning persistent organic pollutants (POPs).
• Forensic Environmental Analysis for source identification and apportionment in pollution incident investigations.

Quality Control

Our high-purity analytical standards are produced and verified under strict quality management protocols. Each batch is characterized using state-of-the-art techniques including high-resolution mass spectrometry and gas chromatography to confirm identity and purity. A comprehensive Certificate of Analysis (COA) is provided with each unit, detailing the certified concentration, measurement uncertainty, and chromatographic purity. Our materials are suitable for use in methods compliant with US EPA, EU, and other international standards for dioxin analysis.

Storage

Preserve in a tightly closed container, protected from light. Store at -10 to -20°C in a dedicated freezer. Due to its highly volatile nature, allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation and loss of material. Store away from strong acids, bases, and oxidizing agents.
