Description

1,2,4,6,7,9/1,2,4,6,8,9-Hexachlorodibenzo-p-Dioxin is a specific chlorinated dioxin congener, a class of compounds of significant environmental and analytical interest. It is primarily utilized as a critical reference standard and analytical standard in environmental monitoring and toxicological research. This compound is essential for laboratories and research institutions focused on persistent organic pollutant (POP) analysis, dioxin fingerprinting, and regulatory compliance testing.

Application

• Environmental Analysis Reference Standard: Used for the calibration and quantification of dioxin congeners in soil, water, sediment, and air samples.
• Toxicological Research: Serves as a precise chemical standard in studies investigating the toxicity, bioaccumulation, and environmental fate of chlorinated dioxins.
• Food and Feed Safety Testing: Employed as an analytical standard in the detection and monitoring of dioxin contamination in the food chain to ensure regulatory compliance.
• Waste and Emission Monitoring: Critical for analyzing industrial emissions and waste incineration by-products to assess environmental impact and control measures.
• Method Development and Validation: Provides a certified reference material for developing and validating high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) methods.
• Quality Control/Quality Assurance (QC/QA): Acts as an internal or external standard in laboratory QC protocols to ensure the accuracy and precision of dioxin analysis.
