Description

1,2,3,6-Tetrachlorodibenzo[1,4]Dioxin 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 is primarily required by environmental testing facilities, regulatory bodies, and chemical manufacturers engaged in the study, monitoring, and remediation of dioxin contamination.

Application

• Analytical Reference Standard: Primary use as a certified standard for the precise calibration and validation of analytical instruments like GC-MS and HRGC-HRMS in dioxin analysis.
• Environmental Monitoring: Used in the quantification and profiling of dioxin congeners in soil, water, air, and sediment samples to assess pollution levels and environmental impact.
• Toxicological Research: Serves as a key material in scientific studies investigating the structure-activity relationships, environmental fate, and toxicological effects of specific chlorinated dioxin isomers.
• Method Development & Validation: Essential for developing, optimizing, and accrediting new laboratory analytical methods for the detection of polychlorinated dibenzo-p-dioxins (PCDDs).
• Quality Assurance/Quality Control (QA/QC): Employed as a spike or control material in laboratory proficiency testing and internal QA/QC programs to ensure data accuracy and reliability.
• Regulatory Compliance Testing: Used by industries (e.g., waste incineration, chemical manufacturing) to test emissions and products for compliance with strict international regulations on dioxin levels (e.g., Stockholm Convention, EU directives).
