Description

1,2,3,7,8-Pentabromodibenzo-p-Dioxin is a highly brominated derivative of dibenzo-p-dioxin, a compound of significant interest in advanced chemical research and development. This specialty chemical serves as a critical reference standard and analytical intermediate for environmental monitoring and toxicological studies of brominated dioxins. It is primarily required by research institutions, analytical laboratories, and chemical manufacturers engaged in environmental analysis, flame retardant research, and the synthesis of complex halogenated compounds.

Application

• Environmental Analytical Reference Standard: Used as a certified standard for the precise quantification and identification of brominated dioxin congeners in environmental samples (air, water, soil, sediment) via GC-MS or HRGC/HRMS.
• Toxicological Research: Serves as a key material in studies investigating the environmental fate, bioaccumulation, and toxicological profiles of polybrominated dibenzo-p-dioxins (PBDDs).
• Flame Retardant Studies: Employed in research to understand the formation mechanisms and by-products of brominated flame retardants during thermal processes.
• Chemical Synthesis Intermediate: Acts as a building block or precursor in the specialized synthesis of other complex halogenated aromatic compounds for research purposes.
• Method Development and Validation: Critical for developing, calibrating, and validating analytical methods in compliance with environmental monitoring protocols.
• Quality Control & Assurance: Used by producers of analytical standards and reagents to ensure the accuracy and reliability of their product offerings.

Quality Control

Our high-purity 1,2,3,7,8-Pentabromodibenzo-p-Dioxin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and reliability for sensitive analytical applications. Each lot is characterized using advanced analytical techniques including high-resolution gas chromatography/mass spectrometry (HRGC/HRMS) and nuclear magnetic resonance (NMR) to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, congener-specific data, and analytical methods is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature, the container should be kept in secondary opaque packaging or amber glass. For long-term storage, consider storing under an inert atmosphere in a freezer (-20°C) to maximize stability.
