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.
(3AS,4S,5aR,9aR,9bS)-4-(benzyloxy)-2,8-diphenylhexahydro-[1,3]dioxolo[4',5':4,5]pyrano[3,2-d][1,3]dioxine (CAS 58650-53-6) is a high-purity analytical reference standard with the molecular formula C27H26O6 and a molecular weight of 446.49 g/mol.
(3AS,4S,5aR,9aR,9bS)-4-(benzyloxy)-2,8-diphenylhexahydro-[1,3]dioxolo[4',5':4,5]pyrano[3,2-d][1,3]dioxine (C27H26O6) contains a steroid core, a hydroxyl group, an ether linkage. 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).
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.
