Chemical Structure
Description
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution, (2,2-Diethoxyethyl)triphenylphosphonium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 459.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(2,2-Diethoxyethyl)triphenylphosphonium bromide (CAS 51605-46-0) is a high-purity analytical reference standard with the molecular formula C24H28O2PBr and a molecular weight of 459.36 g/mol.
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.
