Description

1,3,7,9-Tetrachlorodibenzo-p-Dioxin is a specific, high-purity chlorinated dioxin congener, identified by CAS NO 62470-53-5. This compound is of significant importance as a critical analytical standard and reference material for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and environmental agencies involved in the detection and quantification of persistent organic pollutants (POPs) and dioxin-like compounds.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in environmental analysis.
• Environmental Monitoring: Critical for the accurate quantification of dioxin and furan congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Serves as a key reagent in studies investigating the biological activity, metabolic pathways, and health effects of specific chlorinated dioxin isomers.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods according to EPA, EU, and other international standards.
• Quality Control/Quality Assurance (QC/QA): Used in laboratory proficiency testing and as a spike/recovery standard to ensure the accuracy and precision of analytical data.
• Regulatory Compliance Testing: Supports testing for compliance with global regulations concerning POPs, such as the Stockholm Convention.
• Food & Feed Safety Analysis: Employed in the analysis of dioxin contamination in food chains, including dairy, meat, and fish products.
