Description

2,3,4,6,7-Pentachlorodibenzofuran is a specific, high-purity congener of the polychlorinated dibenzofuran (PCDF) family, a class of compounds of significant environmental and toxicological interest. This compound is primarily utilized as a critical analytical reference standard for precise identification and quantification in complex matrices. It is essential for laboratories and research institutions focused on environmental monitoring, food safety, and toxicological studies, where accurate measurement of persistent organic pollutants (POPs) is mandated by international regulations.

Application

• Analytical Reference Standard for the calibration of GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis for the detection and quantification of dioxin-like compounds in soil, sediment, water, and air samples.
• Food and Feed Safety Testing to monitor contamination levels and ensure compliance with strict international limits (e.g., EU, US FDA).
• Toxicological and Biomedical Research to study the mechanisms of action, bioaccumulation, and health effects of halogenated aromatic hydrocarbons.
• Quality Control and Method Validation in commercial and regulatory testing laboratories.
• Forensic Analysis for source identification and environmental forensics related to industrial accidents or pollution events.
