Description

1,2,4,6-Tetrachlorodibenzo[1,4]Dioxin CAS NO 71669-27-7 is a specific chlorinated derivative of dibenzo-p-dioxin, a compound class of significant interest in environmental and analytical chemistry. This high-purity reference standard is critical for research, method development, and regulatory compliance testing. It is primarily utilized by analytical laboratories, environmental monitoring agencies, and research institutions focused on persistent organic pollutant (POP) analysis and toxicology studies.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration and quantification of dioxin congeners in environmental and biological samples via GC-MS or HRGC/HRMS.
• Environmental Monitoring: Critical for the analysis of soil, water, air, and sediment samples to assess contamination levels and track the fate of chlorinated dioxins.
• Food and Feed Safety Analysis: Used in laboratories to screen for dioxin contamination in the food chain, ensuring compliance with strict international safety regulations (e.g., EU, FDA).
• Toxicological Research: Serves as a precise chemical entity for studying the structure-activity relationships, metabolic pathways, and health impacts of specific dioxin congeners.
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for the detection of polychlorinated dibenzo-p-dioxins (PCDDs).
• Quality Control/Quality Assurance (QC/QA): Employed as an internal or external standard to ensure the accuracy, precision, and reliability of analytical data in testing laboratories.
• Regulatory Compliance Testing: Supports testing mandated by global regulations such as the Stockholm Convention on Persistent Organic Pollutants, REACH, and TSCA.
