Description

1,2,3,4,8-Pncdf CAS NO 67517-48-0 is a specific polychlorinated dibenzofuran (PCDF) congener, a class of compounds of significant environmental and analytical interest. This high-purity analytical standard is essential for research, regulatory compliance, and quality control in environmental monitoring and toxicology studies. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, dioxin/furan profiling, and method development.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration and quantification of PCDFs in environmental and biological samples via high-resolution gas chromatography/mass spectrometry (HRGC/HRMS).
• Environmental Monitoring: Critical for the analysis of soil, sediment, water, and air samples to assess contamination levels and comply with international regulations like the Stockholm Convention on POPs.
• Food and Feed Safety: Employed in the testing of foodstuffs, animal feed, and edible oils for dioxin and furan contamination to ensure consumer safety and meet EU and FDA guidelines.
• Toxicological Research: Serves as a precise congener standard in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Waste and Emission Analysis: Used to monitor and characterize PCDF emissions from industrial processes, incineration, and in waste characterization.
• Method Development and Validation: Essential for developing, optimizing, and validating analytical methods for the separation and detection of specific PCDF congeners in complex matrices.
• Quality Assurance/Quality Control (QA/QC): Acts as a spike or internal standard in laboratory QA/QC protocols to ensure accuracy, precision, and reliability of analytical data.

Quality Control

Our high-purity analytical standards are produced and handled under strict quality-controlled conditions. Each batch of 1,2,3,4,8-Pncdf is rigorously analyzed using state-of-the-art techniques like GC-MS and HPLC to confirm identity and purity, ensuring traceability and reliability for critical applications. A comprehensive Certificate of Analysis (COA) detailing purity, analytical methods, and batch-specific data is provided with every shipment to support your compliance and documentation needs.

Storage

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