Chemical Structure
Description
(1-(Dimethylamino)-1-oxopropan-2-yl)triphenylphosphonium bromide (CAS 198488-16-3) is a high-purity analytical reference standard with the molecular formula C23H25NOPBr and a molecular weight of 442.34 g/mol.
Structurally, (1-(Dimethylamino)-1-oxopropan-2-yl)triphenylphosphonium bromide (C23H25NOPBr) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 442.34 g/mol, it falls into the moderately-high-molecular-weight range. 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.
