(4S,4′S)-2,2′-(5,5′-Dichloro[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] CAS 944133-16-8

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′-(5,5′-Dichloro[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole].

(4S,4′S)-2,2′-(5,5′-Dichloro[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] (CAS 944133-16-8) is a high-purity analytical reference standard with the molecular formula C30H22Cl2N2O2 and a molecular weight of 513.41 g/mol.

(4S,4′S)-2,2′-(5,5′-Dichloro[1,1′-biphenyl]-2,2′-diyl)bis[4,5-dihydro-4-phenyloxazole] (C30H22Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
