Description

1,2,3,4,6,7,8-Heptachloro-Dibenzofuran-13C12 is a stable isotope-labeled analog of a polychlorinated dibenzofuran (PCDF), where all twelve carbon atoms are the carbon-13 (13C) isotope. This compound serves as a critical internal standard for the precise quantification and confirmation of its native counterpart in complex environmental and biological matrices. It is essential for analytical laboratories requiring the highest level of accuracy in trace-level analysis for regulatory compliance and research. Target users include environmental testing facilities, food safety labs, and research institutions focused on dioxin and persistent organic pollutant (POP) analysis.

Application

• Internal Standard for Mass Spectrometry: Primary use as a quantitative and qualitative internal standard in Gas Chromatography-Mass Spectrometry (GC-MS) and High-Resolution GC-MS (HRGC-HRMS) for dioxin analysis.
• Environmental Monitoring: Calibration and recovery studies in the analysis of soil, sediment, water, and air samples for polychlorinated dibenzofurans (PCDFs).
• Food and Feed Safety Testing: Essential for accurate quantification of PCDF contaminants in food, animal feed, and edible oils to ensure compliance with global safety regulations (e.g., EU, FDA).
• Biomonitoring and Clinical Research: Used in the analysis of human blood, serum, and tissue samples to assess exposure levels and study the toxicokinetics of persistent organic pollutants.
• Method Development and Validation: Critical component for developing, optimizing, and validating new analytical methods for dioxin-like compounds.
• Quality Assurance/Quality Control (QA/QC): Employed in proficiency testing and inter-laboratory comparisons to ensure data accuracy and reliability.
• Waste and Emission Analysis: Testing of industrial waste, incineration flue gases, and other emission sources for regulatory control of POPs.
