The molecular framework of (5Z)-5-{[4-(propan-2-yl)phenyl]methylidene}-3-[(pyridin-3-yl)methyl]-2-sulfanylideneimidazolidin-4-one (C19H19N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
(5Z)-5-{[4-(propan-2-yl)phenyl]methylidene}-3-[(pyridin-3-yl)methyl]-2-sulfanylideneimidazolidin-4-one (CAS 320422-92-2), molecular formula C19H19N3OS and molecular weight 337.44 g/mol, is a CATO reference standard with documented purity and traceability.
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.
