Description

1,2,3,4,7,8-Hexachlorodibenzo-p-Dioxin is a specific, high-purity congener of polychlorinated dibenzo-p-dioxins (PCDDs), a class of compounds of significant environmental and toxicological interest. This compound serves as a critical analytical reference standard for precise quantification and regulatory compliance testing. It is primarily required by environmental testing laboratories, research institutions, and regulatory bodies engaged in the analysis of dioxin contamination in various matrices.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS and HRGC/HRMS systems in dioxin analysis.
• Environmental Monitoring: Quantification of PCDD/Fs in soil, sediment, water, and air samples to assess pollution levels and compliance with environmental regulations.
• Food and Feed Safety Analysis: Critical for testing dioxin levels in food products, animal feed, and edible oils to ensure public health safety and adherence to maximum residue limits (MRLs).
• Toxicological Research: Used in scientific studies to investigate the specific toxicokinetics, metabolism, and health effects of individual dioxin congeners.
• Waste and Emission Control: Analysis of industrial emissions, incinerator fly ash, and chemical waste to monitor and control dioxin release.
• Quality Assurance/Quality Control (QA/QC): Serves as a spike or recovery standard in analytical procedures to validate method accuracy and precision.
• Regulatory Compliance Testing: Essential for laboratories performing mandatory testing to comply with global regulations such as EU, US EPA, and JIS methods.

Quality Control

Our high-purity analytical standards are produced and verified under strict quality management protocols. Each batch is characterized using advanced techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) to confirm identity and purity. We provide comprehensive Certificates of Analysis (COA) detailing the certified concentration, uncertainty, analytical methods, and traceability to relevant standards. Our quality system supports compliance with ISO/IEC 17025 requirements for reference material producers.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. For long-term storage, keep at -20°C or below under inert atmosphere. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
