Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 543.87 g/mol gives Tetrabromobisphenol A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetrabromobisphenol A (CAS 79-94-7) is a high-purity analytical reference standard with the molecular formula C15H12Br4O2 and a molecular weight of 543.87 g/mol.
The molecular framework of Tetrabromobisphenol A (C15H12Br4O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
