Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4S,4′S)-2,2′-(1,4-Phenylene)bis[4-(1,1-dimethylethyl)-4,5-dihydrooxazole].
CATO supplies (4S,4′S)-2,2′-(1,4-Phenylene)bis[4-(1,1-dimethylethyl)-4,5-dihydrooxazole] (CAS 906672-95-5), a certified reference material (molecular formula C20H28N2O2, MW 328.45 g/mol) for analytical method development and quality control.
Structurally, (4S,4′S)-2,2′-(1,4-Phenylene)bis[4-(1,1-dimethylethyl)-4,5-dihydrooxazole] (C20H28N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 328.45 g/mol, it falls into the moderately-high-molecular-weight range. 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).
