Description

2,3,7,8-Tetrabromodibenzofuran is a high-purity, polybrominated dibenzofuran compound, serving as a critical reference standard and research chemical. Its primary value lies in its role as a model compound for studying the environmental behavior and toxicology of brominated flame retardants and dioxin-like substances. This product is essential for analytical laboratories, environmental research institutions, and regulatory bodies involved in persistent organic pollutant (POP) analysis and material safety testing.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration and validation of analytical methods like GC-MS and HPLC in environmental and food testing laboratories.
• Environmental Fate Studies: Used as a tracer or model compound in research investigating the degradation, bioaccumulation, and transport of brominated dioxins and furans in ecosystems.
• Toxicological Research: Serves as a key substance in studies assessing the endocrine-disrupting effects, carcinogenicity, and other health impacts of brominated aromatic compounds.
• Method Development: Critical for developing and optimizing new analytical protocols for the detection and quantification of polybrominated dibenzofurans (PBDFs) in complex matrices.
• Quality Control & Assurance: Employed in internal quality control procedures to ensure the accuracy and precision of analytical data generated for regulatory compliance (e.g., EPA, EU directives).
• Material Science Research: Used in studies related to the formation and inhibition of brominated dioxins during thermal processes involving brominated flame retardants.
