Description

1,3,7,8-Tetrachlorodibenzo-p-Dioxin is a specific chlorinated congener of the dioxin chemical family, identified by CAS NO 50585-46-1. This compound is of significant importance as a high-purity analytical reference standard for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the detection and study of persistent organic pollutants (POPs).

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: Quantification and confirmation of dioxin contamination in soil, water, sediment, and air samples.
• Food and Feed Safety Testing: Used in methods to determine dioxin levels to ensure compliance with strict international safety regulations (e.g., EU, FDA).
• Method Development and Validation: Essential for developing, optimizing, and validating new analytical protocols for dioxin detection.
• Quality Control/Quality Assurance (QC/QA): Used in proficiency testing and inter-laboratory comparisons to ensure accuracy and consistency of analytical results.
• Regulatory Compliance and Certification: Supports testing for compliance with international treaties like the Stockholm Convention on POPs.
