Description

1,2,8,9-Tetrachlorodibenzo-Para-Dioxin CAS NO 62470-54-6 is a specific chlorinated derivative of dibenzo-p-dioxin, a compound class of significant interest in environmental and analytical chemistry. This high-purity reference material is critical for research, method development, and quality control in laboratories focused on persistent organic pollutant (POP) analysis. It serves as an essential standard for scientists and technicians in environmental monitoring, toxicology studies, and regulatory compliance testing, enabling precise calibration and accurate identification in complex matrices.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for the quantification of polychlorinated dibenzo-p-dioxins (PCDDs) in soil, water, air, and biological samples.
• Toxicological Research: Used in laboratory studies to investigate the specific biological activity, metabolic pathways, and toxic effects of tetrachlorinated dioxin congeners.
• Analytical Method Development & Validation: Essential for developing, optimizing, and validating high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) and other analytical methods for dioxin analysis.
• Quality Assurance/Quality Control (QA/QC): Employed as a spike or internal standard to assess method recovery, accuracy, and precision in commercial and regulatory testing laboratories.
• Calibration Standard: Used to prepare calibration curves for congener-specific analysis, ensuring reliable and traceable measurement results.
• Regulatory Compliance Testing: Supports testing mandated by international regulations (e.g., Stockholm Convention, EU directives) governing POPs in industrial emissions, waste, and consumer products.
