Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 477.38 g/mol gives (4-Ethoxybenzyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4-Ethoxybenzyl)triphenylphosphonium bromide (CAS 82105-88-2), a certified reference material (molecular formula C27H26OPBr, MW 477.38 g/mol) for analytical method development and quality control.
(4-Ethoxybenzyl)triphenylphosphonium bromide (C27H26OPBr) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
