Description

Dibenzo(B,E)(1,4)Dioxin, Hexachloro is a specific, high-purity polychlorinated dibenzo-p-dioxin (PCDD) congener, widely recognized in analytical and research chemistry. This compound is of critical importance as a certified reference material and analytical standard for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on dioxin analysis, food safety, and persistent organic pollutant (POP) studies to ensure accurate calibration and quantification.

Application

• Primary use as a certified reference standard (CRM) for the calibration of GC-MS and HRGC-HRMS systems in dioxin analysis.
• Critical component in environmental monitoring programs for soil, water, and air to detect and quantify PCDD contamination.
• Essential for food and feed safety analysis, ensuring compliance with strict international regulations on dioxin levels.
• Used in toxicological and eco-toxicological research to study the effects and behavior of specific dioxin congeners.
• Serves as a quality control (QC) standard in commercial and regulatory laboratories performing US EPA Method 1613 or similar protocols.
• Applied in waste incineration and industrial emission studies to fingerprint and quantify dioxin outputs.
• Utilized for the development and validation of new analytical methods for persistent organic pollutants (POPs).
