Chemical Structure
Description
The molecular framework of Potassium 5-(4-(2-(5-ethylpyridin-2-yl)ethoxy)benzyl)-2,4-dioxothiazolidin-3-ide (C19H19N2O3SK) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Potassium 5-(4-(2-(5-ethylpyridin-2-yl)ethoxy)benzyl)-2,4-dioxothiazolidin-3-ide (CAS 1266523-09-4) is a high-purity analytical reference standard with the molecular formula C19H19N2O3SK and a molecular weight of 394.53 g/mol.
