(2-(4-Aminophenyl)-2-oxoethyl)triphenylphosphonium bromide CAS 1101778-71-5

Description

Compared with other compounds in its class, the molecular weight of 476.35 g/mol gives (2-(4-Aminophenyl)-2-oxoethyl)triphenylphosphonium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2-(4-Aminophenyl)-2-oxoethyl)triphenylphosphonium bromide (CAS 1101778-71-5) is a high-purity analytical reference standard with the molecular formula C26H23NOPBr and a molecular weight of 476.35 g/mol.

(2-(4-Aminophenyl)-2-oxoethyl)triphenylphosphonium bromide (C26H23NOPBr) contains a steroid core, an amide group, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
