Description

2,7-Dichlorodibenzo-p-Dioxin is a specific chlorinated derivative of the dibenzo-p-dioxin chemical class. This compound is of significant interest in environmental and analytical chemistry as a model compound and reference standard for studying the behavior and toxicity of polychlorinated dibenzo-p-dioxins (PCDDs). It is primarily required by research institutions, analytical laboratories, and chemical manufacturers involved in environmental monitoring, toxicological studies, and the development of detection methods for persistent organic pollutants.

Application

• Analytical Reference Standard: Used as a high-purity certified reference material (CRM) for the calibration of GC-MS and HPLC systems in environmental testing laboratories.
• Toxicological Research: Serves as a specific congener for studying the structure-activity relationships, metabolic pathways, and environmental fate of chlorinated dioxins.
• Method Development & Validation: Critical for developing and validating analytical methods for the detection and quantification of PCDDs in complex matrices like soil, water, and biological tissues.
• Environmental Fate Studies: Employed in research to understand the degradation, bioaccumulation, and transport of dioxin-like compounds in ecosystems.
• Quality Control Material: Used by chemical producers and regulatory bodies as a QC check sample to ensure the accuracy of dioxin analysis in industrial emissions or waste.
• Chemical Synthesis Intermediate: Acts as a building block or precursor in specialized organic synthesis for creating other halogenated aromatic compounds for research purposes.
