Description

1,2,4,8,9-Pentachlorodibenzodioxin is a specific, high-purity chlorinated dibenzodioxin congener used primarily as a critical reference standard and analytical reagent. Its precise chemical structure makes it an essential tool for environmental monitoring, toxicological research, and regulatory compliance testing. This compound is vital for laboratories and research institutions focused on dioxin analysis, method development, and quality control in environmental and food safety sectors.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Environmental Monitoring: Used in the quantification and confirmation of dioxin and furan congeners in soil, sediment, water, and air samples.
• Food and Feed Safety Testing: Essential for accurate measurement of dioxin contamination levels to ensure compliance with strict EU and international regulations (e.g., EU 1259/2011, WHO-TEFs).
• Toxicological and Biomedical Research: Serves as a specific congener for studying the structure-activity relationships, metabolism, and health effects of polychlorinated dibenzodioxins (PCDDs).
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods according to EPA 1613B, EPA 8290, and other standardized protocols.
• Quality Assurance/Quality Control (QA/QC): Used as an internal or recovery standard in laboratory proficiency testing and to ensure the accuracy and precision of analytical data.
