Description

1,2,3,4,6,7,9-Heptachlorodibenzo-p-Dioxin is a specific, highly chlorinated congener of the polychlorinated dibenzo-p-dioxin (PCDD) family, a group of compounds of significant environmental and analytical interest. This compound is primarily utilized as a critical reference standard and analytical standard for precise identification and quantification in complex matrices. It is essential for industries and research institutions focused on environmental monitoring, food safety, and toxicological studies, where accurate measurement of dioxin contamination is paramount for regulatory compliance and risk assessment.

Application

• Environmental Analysis: Calibration standard for the detection and quantification of PCDDs in soil, sediment, water, and air samples.
• Food and Feed Safety Testing: Reference material in accredited laboratories for analyzing dioxin levels in food products, animal feed, and edible oils to ensure compliance with strict international safety limits (e.g., EU, FDA).
• Toxicological and Biomedical Research: Used in studies investigating the environmental fate, metabolic pathways, and specific toxic effects of heptachlorinated dioxin congeners.
• Waste and Emission Monitoring: Critical for analyzing industrial emissions, incinerator fly ash, and chemical waste to monitor and control dioxin release.
• Quality Control and Method Development: Serves as a system suitability check and validation standard in high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) methods.
• Regulatory Compliance and Certification: Provides the benchmark for testing laboratories to certify their analytical results against regulatory requirements set by bodies like the EPA and EFSA.
