Description

1,2,3,4,9-Pncdf CAS NO 83704-49-8 is a specific polychlorinated dibenzofuran (PCDF) congener, a class of compounds of significant environmental and analytical interest. It serves as a critical reference standard and analytical standard for precise identification and quantification in complex matrices. This high-purity material is essential for research laboratories, environmental testing facilities, and regulatory bodies engaged in monitoring persistent organic pollutants (POPs) and ensuring compliance with international safety protocols.

Application

• Analytical Reference Standard: Primary use as a certified standard for calibrating equipment like GC-MS and HPLC in environmental and food safety testing.
• Environmental Analysis: Quantification and monitoring of dioxin-like compounds in soil, water, sediment, and air samples to assess contamination levels.
• Food and Feed Safety Testing: Used in methods to detect and quantify PCDFs in food chains, ensuring compliance with EU and global maximum residue limits (MRLs).
• Toxicological Research: Serves as a precise congener in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods for POPs analysis in accredited laboratories.
• Quality Control/Quality Assurance (QC/QA): Used as an internal or external standard to verify the accuracy and precision of analytical results in routine testing.
• Regulatory Compliance Testing: Supports testing mandated by regulations such as the Stockholm Convention, EPA methods, and EU directives.
