1-(3-(4-(Methylsulfonyl)piperidin-1-yl)benzyl)-5-(3-(4-(trifluoromethoxy)phenyl)isoxazol-5-yl)pyridin-2(1H)-one (CAS 1571034-39-3) is a high-purity analytical reference standard with the molecular formula C28H26F3N3O5S and a molecular weight of 573.58 g/mol.
The molecular framework of 1-(3-(4-(Methylsulfonyl)piperidin-1-yl)benzyl)-5-(3-(4-(trifluoromethoxy)phenyl)isoxazol-5-yl)pyridin-2(1H)-one (C28H26F3N3O5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
