Chemical Structure
Description
(4S,4′S)-2,2′-(1,8-Anthracenediyl)bis[4,5-dihydro-4-[(1S)-1-methylpropyl]oxazole] (CAS 873843-21-1) is a high-purity analytical reference standard with the molecular formula C28H32N2O2 and a molecular weight of 428.57 g/mol.
(4S,4′S)-2,2′-(1,8-Anthracenediyl)bis[4,5-dihydro-4-[(1S)-1-methylpropyl]oxazole] (C28H32N2O2) 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.
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.
