Chemical Structure
Description
The molecular framework of 5-(4-Methoxyphenyl)-1-(2-propylpentanoyl)pyrazolidin-3-one (C18H26N2O3) is characterized by a steroid core, an amide 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
5-(4-Methoxyphenyl)-1-(2-propylpentanoyl)pyrazolidin-3-one (CAS 740812-33-3) is a high-purity analytical reference standard with the molecular formula C18H26N2O3 and a molecular weight of 318.41 g/mol.
