Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 415.51 g/mol gives (4S)-2-[1-[2-(Diphenylphosphino)phenyl]-1-methylethyl]-4,5-dihydro-4-(1-methylethyl)oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4S)-2-[1-[2-(Diphenylphosphino)phenyl]-1-methylethyl]-4,5-dihydro-4-(1-methylethyl)oxazole (CAS 947618-06-6), molecular formula C27H30NOP and molecular weight 415.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (4S)-2-[1-[2-(Diphenylphosphino)phenyl]-1-methylethyl]-4,5-dihydro-4-(1-methylethyl)oxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
