Description

2,3,4,7,8-Pentabromodibenzofuran is a high-purity, polybrominated dibenzofuran congener with the CAS number 131166-92-2. This compound is a critical reference standard and analytical reagent for environmental monitoring and toxicological research. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the study of persistent organic pollutants (POPs), flame retardant degradation, and dioxin-like compounds.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification of polybrominated dibenzofurans (PBDFs) in soil, water, sediment, and air samples via GC-MS or HRGC/HRMS.
• Toxicological Research: Serves as a key analyte in studies investigating the environmental fate, bioaccumulation, and toxic effects (e.g., endocrine disruption, carcinogenicity) of brominated flame retardant by-products.
• Food and Feed Safety Testing: Employed in method development and validation for detecting PBDF contaminants in food chains and animal feed, ensuring compliance with safety regulations.
• Quality Control and Method Validation: Essential for calibrating analytical instruments, assessing method recovery rates, and ensuring the accuracy and precision of laboratory testing protocols for halogenated persistent organic pollutants.
• Regulatory Compliance and Monitoring: Supports laboratories in meeting global regulatory requirements for POPs monitoring under treaties like the Stockholm Convention, as well as regional directives.
• Material Science Research: Used in studies analyzing the formation and emission of PBDFs from the thermal degradation of brominated flame retardants in polymers and electronic waste.
