Description

1,2,3,4-Tetrabromo-7,8-Dichlorodibenzo-Para-Dioxin is a halogenated dibenzo-p-dioxin derivative of significant interest in advanced chemical research and development. This compound matters as a high-purity, structurally defined reference standard and a critical synthetic intermediate for specialized applications. It is primarily needed by analytical laboratories, research institutions, and specialty chemical manufacturers working in environmental analysis, toxicology studies, and the development of flame-retardant materials or novel halogenated compounds.

Application

• Analytical Reference Standard: Used for the calibration of instruments and as a certified standard in gas chromatography-mass spectrometry (GC-MS) for the detection and quantification of polyhalogenated dioxins and furans in environmental samples.
• Toxicological Research: Serves as a model compound in studies investigating the structure-activity relationships, environmental fate, and biological impact of halogenated dioxins.
• Chemical Synthesis Intermediate: Acts as a key building block in the research-scale synthesis of more complex polyhalogenated aromatic systems for material science applications.
• Flame Retardant Research: Investigated for its potential use in the development of novel, high-performance flame-retardant additives or polymers due to its high bromine and chlorine content.
• Method Development & Validation: Employed by testing laboratories to develop, optimize, and validate analytical methods for persistent organic pollutants (POPs) under regulatory frameworks.
