Description

1,2,3,7-Tetrachlorodibenzo[1,4]Dioxin CAS NO 67028-18-6 is a specific, high-purity chlorinated dioxin congener of significant interest for analytical and research purposes. This compound is critical for laboratories and industries requiring precise reference standards for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily utilized by analytical chemists, environmental scientists, and regulatory bodies focused on the detection and quantification of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Serves as a certified reference material (CRM) for the calibration of GC-MS, HRGC/HRMS, and other analytical instrumentation.
• Environmental Analysis: Used in the quantification and method development for detecting dioxin contamination in soil, water, air, and biological samples.
• Toxicological Research: Essential for studying the specific biological activity, metabolism, and health impact profiles of individual dioxin congeners.
• Food and Feed Safety Testing: Employed as a standard in laboratories ensuring compliance with maximum residue levels (MRLs) for dioxins in the food chain.
• Quality Control and Assurance: Used by manufacturers of analytical kits and laboratories to validate testing procedures and ensure accuracy.
• Regulatory Compliance and Method Validation: Critical for laboratories to demonstrate proficiency and comply with international standards (e.g., EPA, EU) for dioxin analysis.
