Description

1,2,6,7-Tetrachlorodibenzo-p-Dioxin is a specific chlorinated derivative of dibenzo-p-dioxin, a class of compounds of significant interest in environmental and analytical chemistry. This high-purity reference standard is critical for research, method development, and quality control in laboratories focused on persistent organic pollutant (POP) analysis. It is primarily utilized by environmental testing facilities, regulatory bodies, and academic research institutions engaged in the detection and quantification of dioxin and furan congeners.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC-HRMS systems in environmental analysis.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical procedures for dioxin congener separation and detection.
• Quality Assurance/Quality Control (QA/QC): Used in laboratory proficiency testing, spike/recovery studies, and as an internal or external standard to ensure analytical accuracy.
• Environmental Monitoring & Research: Supports studies on the fate, transport, and toxicological profile of chlorinated dioxins in soil, water, and biological samples.
• Regulatory Compliance Testing: Enables testing to comply with international regulations (e.g., Stockholm Convention, EU directives) governing POPs in industrial emissions and consumer products.
• Toxicological Studies: Serves as a research chemical in scientific investigations exploring the structure-activity relationships and health effects of dioxin-like compounds.
