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 high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) systems in dioxin analysis.
• Analytical Method Development & Validation for establishing and verifying protocols to detect trace levels of PCDFs.
• Environmental Monitoring & Forensics to identify contamination sources and assess pollution levels in compliance with international treaties like the Stockholm Convention.
• Toxicological & Ecotoxicological Research to study the congener-specific effects, bioaccumulation, and metabolic pathways of dioxin-like compounds.
• Quality Control/Quality Assurance (QC/QA) in commercial and government laboratories performing routine dioxin testing on food, feed, and industrial emissions.
• Regulatory Compliance Testing for industries required to monitor their emissions and waste for persistent organic pollutants (POPs).

Quality Control

Our 1,2,3,4,7,8-Hexachlorodibenzofuran is manufactured and handled under strict quality protocols to ensure identity, purity, and stability for its use as a high-grade reference material. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity (typically ≥98% by GC), congener-specific identity confirmation, and chromatographic profile. Our quality system is designed to support ISO/IEC 17025 accredited laboratories and meet the stringent requirements for analytical standards in environmental and food safety testing.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. For long-term stability, store under inert atmosphere. Keep away from heat and sources of ignition.
