Description

1,2,4,6,7-Pentachlorodibenzo[1,4]Dioxin is a specific chlorinated congener of the dioxin chemical family, recognized for its role as a critical reference standard and analytical reagent. This compound matters significantly for environmental monitoring, toxicological research, and regulatory compliance testing due to its relevance in persistent organic pollutant (POP) analysis. It is primarily needed by analytical laboratories, research institutions, and environmental agencies engaged in the precise identification and quantification of dioxin and furan contaminants in complex matrices.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC/HRMS systems in environmental and food testing laboratories.
• Toxicological Research: Serves as a key compound in studies investigating the environmental fate, bioaccumulation, and specific toxic effects of chlorinated dioxins.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods according to protocols from the US EPA, EU, and other international bodies.
• Quality Control/Quality Assurance (QC/QA): Used in proficiency testing and as a spike/recovery standard to ensure the accuracy and precision of analytical data in commercial testing labs.
• Regulatory Compliance Testing: Critical for analyzing samples to ensure compliance with global regulations concerning dioxin levels in emissions, industrial waste, soil, and food products.
• Environmental Forensics: Employed in source identification and apportionment studies to trace the origin of dioxin contamination in the environment.
