(S)-2-(2-(bis(4-(trifluoromethyl)phenyl)phosphanyl)-5-methoxyphenyl)-4-(tert-butyl)-4,5-dihydrooxazole CAS 944836-20-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-(2-(bis(4-(trifluoromethyl)phenyl)phosphanyl)-5-methoxyphenyl)-4-(tert-butyl)-4,5-dihydrooxazole.

(S)-2-(2-(bis(4-(trifluoromethyl)phenyl)phosphanyl)-5-methoxyphenyl)-4-(tert-butyl)-4,5-dihydrooxazole (CAS 944836-20-8), molecular formula C28H26F6NO2P and molecular weight 553.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-2-(2-(bis(4-(trifluoromethyl)phenyl)phosphanyl)-5-methoxyphenyl)-4-(tert-butyl)-4,5-dihydrooxazole (C28H26F6NO2P) contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.5, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 553.48 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
