Description

2,8-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 toxicology of polychlorinated dibenzo-p-dioxins (PCDDs). It is primarily required by research institutions, environmental testing laboratories, and chemical manufacturers engaged in the development of analytical methods, toxicological studies, and quality control of related chemical processes.

Application

• Analytical Reference Standard: Used as a high-purity certified reference material (CRM) for the calibration of GC-MS and HPLC systems in environmental pollutant analysis.
• Environmental Research: Serves as a critical model compound in scientific studies investigating the environmental fate, transport, and degradation pathways of dioxin-like compounds.
• Toxicological Studies: Employed in laboratory research to understand the structure-activity relationships (SAR) and biological impact of specific chlorination patterns on dioxin toxicity.
• Method Development: Essential for developing and validating new analytical techniques for the detection and quantification of PCDDs in complex matrices like soil, water, and biological tissues.
• Quality Control: Used by chemical producers as an internal standard to monitor processes and ensure the purity of related chemical products or to check for the formation of trace dioxin impurities.
• Regulatory Compliance Testing: Supports laboratories performing compliance testing for industries regulated under environmental protection guidelines concerning dioxin emissions.
