Description

2,3,4,6-Tcdf CAS NO 83704-30-7 is a specific congener of tetrachlorodibenzofuran, a class of chlorinated aromatic compounds. This high-purity analytical standard is critical for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and environmental agencies involved in the detection and quantification of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Used as a certified standard for the calibration and validation of analytical instruments like GC-MS and HRGC/HRMS in environmental analysis.
• Environmental Monitoring: Essential for testing soil, water, sediment, and air samples for dioxin and furan contamination as per EPA and other international methods.
• Toxicological Research: Serves as a key material in studies investigating the toxicity, environmental fate, and bioaccumulation of chlorinated dibenzofurans.
• Food and Feed Safety: Employed in the analysis of foodstuffs and animal feed to ensure compliance with maximum residue limits (MRLs) for dioxin-like compounds.
• Quality Control & Method Development: Used by chemical manufacturers and testing laboratories to develop and verify analytical methods for impurity profiling.
• Regulatory Compliance: Supports testing mandated by global regulations such as the Stockholm Convention on POPs, EU directives, and national environmental protection laws.
