Chemical Structure
Description
The molecular framework of 4-Oxo-2-(p-tolyl)-1,4-dihydroquinoline-6-carboxylic acid (C17H13NO3) 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 its high hydrophobicity (logP), 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).
4-Oxo-2-(p-tolyl)-1,4-dihydroquinoline-6-carboxylic acid (CAS 90034-30-3) is a high-purity analytical reference standard with the molecular formula C17H13NO3 and a molecular weight of 279.29 g/mol.
