(4S,4′S)-2,2′-(1,3-Phenylene)bis[4,5-dihydro-4-phenyloxazole] (CAS 876953-19-4), molecular formula C24H20N2O2 and molecular weight 368.43 g/mol, is a CATO reference standard with documented purity and traceability.
(4S,4′S)-2,2′-(1,3-Phenylene)bis[4,5-dihydro-4-phenyloxazole] (C24H20N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
