Description

1,3,4,6,7,9-Hexachlorodibenzofuran is a specific, high-purity chlorinated dibenzofuran congener, identified by CAS NO 92341-05-4. This compound is of significant importance as a critical reference standard and analytical reagent for environmental monitoring and toxicological research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies involved in the detection and quantification of persistent organic pollutants (POPs), particularly dioxins and furans, in environmental matrices, industrial emissions, and biological samples.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating analytical instruments like GC-MS and HRGC-HRMS in the quantification of polychlorinated dibenzofurans (PCDFs).
• Toxicological and Biomedical Research: Serves as a precise chemical standard in studies investigating the toxicity, environmental fate, bioaccumulation, and health effects of dioxin-like compounds.
• Regulatory Compliance Testing: Essential for laboratories performing compliance testing for international treaties like the Stockholm Convention, as well as national regulations on dioxin emissions from waste incineration and industrial processes.
• Food and Feed Safety Monitoring: Used in the analysis of dioxin and furan contamination levels in food, animal feed, and related products to ensure public health safety.
• Method Development and Validation: A key component in developing, validating, and verifying analytical methods for the trace-level detection of halogenated aromatic hydrocarbons.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal or external standard in laboratory QC protocols to ensure the accuracy and precision of analytical data.

Quality Control

Our high-purity reference standards are produced and handled under strict quality-controlled conditions to ensure identity, purity, and stability. Each batch is thoroughly characterized using advanced analytical techniques including gas chromatography-mass spectrometry (GC-MS) and high-resolution mass spectrometry (HRMS). A comprehensive Certificate of Analysis (COA) is provided, detailing the certified purity, analytical methods, and chromatographic data. Our quality system supports compliance with relevant guidelines for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the label or Certificate of Analysis. For long-term storage, keep at -20°C under inert atmosphere. Allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
