(4S,4′S)-2,2′-(1,4-Phenylene)bis[4,5-dihydro-4-(1-methylethyl)oxazole] CAS 131380-87-5

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[4,5-dihydro-4-(1-methylethyl)oxazole].

CATO supplies (4S,4′S)-2,2′-(1,4-Phenylene)bis[4,5-dihydro-4-(1-methylethyl)oxazole] (CAS 131380-87-5), a certified reference material (molecular formula C18H24N2O2, MW 300.40 g/mol) for analytical method development and quality control.

Structurally, (4S,4′S)-2,2′-(1,4-Phenylene)bis[4,5-dihydro-4-(1-methylethyl)oxazole] (C18H24N2O2) 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 300.40 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.
