Description

1,2,4,8-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 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 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.
• Environmental Monitoring: Critical for the accurate identification and quantification of dioxin-like compounds in soil, water, sediment, and air samples to assess contamination levels.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical protocols for chlorinated dioxin detection in complex matrices.
• Quality Assurance/Quality Control (QA/QC): Used in laboratory proficiency testing, internal quality control programs, and to verify the accuracy of analytical results.
• Toxicological & Environmental Fate Studies: Serves as a specific congener for research into the environmental behavior, persistence, and toxicological profile of chlorinated dioxins.
• Regulatory Compliance Testing: Supports testing to ensure compliance with international regulations concerning POPs, such as the Stockholm Convention.
