Description

1,2,3,7,8,9-Hexachlorodibenzo-p-Dioxin-13C12 is a stable isotope-labeled analog of a specific hexachlorinated dioxin congener, where all 12 carbon atoms are replaced with the carbon-13 isotope. This product is essential for precise analytical quantification and method validation in environmental and toxicological research, serving as a critical internal standard. It is primarily required by analytical laboratories, regulatory testing facilities, and research institutions engaged in high-accuracy dioxin analysis.

Application

• Primary use as an internal standard in isotope dilution high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) for dioxin analysis.
• Quantification and method validation in the analysis of environmental samples (soil, water, air particulates) for persistent organic pollutant (POP) monitoring.
• Calibration standard for ensuring accuracy and precision in food and feed safety testing for dioxin contamination.
• Critical reference material in toxicological studies and research on the environmental fate and bioaccumulation of polychlorinated dibenzo-p-dioxins (PCDDs).
• Quality control and assurance in commercial testing laboratories complying with EPA, EU, and other international regulatory methods.
• Use in the development and certification of certified reference materials (CRMs) for dioxins and furans.

Quality Control

Our isotope-labeled standards are produced and verified under strict quality protocols to ensure the highest chemical and isotopic purity for trace-level analysis. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing the isotopic enrichment, chemical purity (by GC/MS), and congener-specific identity, supporting compliance with rigorous methods like EPA 1613 and EU regulations. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -10 to -20°C in a dedicated freezer. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation. Solutions should be prepared in appropriate, non-interfering organic solvents and stored under inert conditions.
