Description

Dibenzo(B,E)(1,4)-Dioxin, Pentachloro- is a specific chlorinated dibenzo-p-dioxin derivative, a compound class of significant interest in chemical research and environmental analysis. Its defined structure makes it a valuable reference standard and a key intermediate in the synthesis of more complex halogenated aromatic systems. This high-purity compound is primarily required by analytical laboratories, research institutions, and specialty chemical manufacturers. It serves as a critical tool for method development, calibration, and toxicological studies related to dioxin-like compounds.

Application

• Analytical Reference Standard: Primary use for the calibration of GC-MS, HPLC, and other analytical instruments in environmental and food safety testing for dioxin and furan analysis.
• Toxicological Research: Used as a defined congener in studies investigating the environmental fate, bioaccumulation, and toxic mechanisms of polychlorinated dibenzo-p-dioxins (PCDDs).
• Chemical Synthesis Intermediate: Serves as a building block or precursor in the synthesis of other halogenated aromatic compounds for advanced material or pharmaceutical research.
• Method Development & Validation: Essential for developing and validating analytical methods in compliance with regulatory frameworks like EPA Method 1613 and 8290.
• Quality Control & Assurance: Employed in laboratory quality control protocols to ensure the accuracy and precision of dioxin analysis in complex matrices.
• Environmental Forensics: Acts as a marker or tracer in studies aiming to identify sources and pathways of dioxin contamination in the environment.
