Chemical Structure
Description
CATO supplies 2,2',3,4',5-Pentabromodiphenyl ether (CAS 446254-57-5), a certified reference material (molecular formula C12H5Br5O, MW 564.69 g/mol) for analytical method development and quality control.
2,2',3,4',5-Pentabromodiphenyl ether (C12H5Br5O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
