Description

1,2,3,4,7,8-Hexachlorodibenzofuran 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 analytical instruments (GC-MS, HRGC/HRMS) in environmental testing.
• Analytical Method Development and validation for the precise quantification of PCDFs and dioxins.
• Toxicological and Ecotoxicological Research to study the environmental fate, bioaccumulation, and health effects of dioxin-like compounds.
• Quality Control/Quality Assurance (QC/QA) in laboratories performing compliance testing for international regulations (e.g., Stockholm Convention, EU directives).
• Forensic Environmental Analysis for source identification and apportionment in contamination incidents.
• Preparation of Calibration Solutions and Spikes for internal and external laboratory proficiency testing.

Quality Control

Our high-purity 1,2,3,4,7,8-Hexachlorodibenzofuran is manufactured and handled under strict quality protocols to ensure identity, purity, and stability for critical analytical applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity (typically ≥98% by GC), confirmatory identification data, and chromatographic profile. Our quality system is designed to support compliance with ISO 17034 requirements 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 product label or Certificate of Analysis. For long-term storage, consider storage at -20°C. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
