Description

1,2,4,8-Tcdf CAS NO 64126-87-0 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 primary standard for the calibration of GC-MS and HRGC/HRMS systems in environmental analysis.
• Environmental Monitoring: Essential for testing soil, water, sediment, and air samples for dioxin and furan contamination as per EPA and international guidelines.
• Toxicological Research: Serves as a key compound 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/Assurance: Used by manufacturers and testing laboratories to validate analytical methods and ensure the accuracy of internal quality control programs.
• Regulatory Compliance: Supports testing mandated by regulations such as the Stockholm Convention on POPs, EU Directive 2011/65/EU (RoHS), and EPA Method 1613.
