Ethyl 5-hydroxy-8-isopropyl-7-oxo-2-phenyl-7,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylate CAS 1253790-73-6

Description

The molecular framework of Ethyl 5-hydroxy-8-isopropyl-7-oxo-2-phenyl-7,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylate (C19H19N3O4) is characterized by a flavonoid 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).

Ethyl 5-hydroxy-8-isopropyl-7-oxo-2-phenyl-7,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylate (CAS 1253790-73-6) is a high-purity analytical reference standard with the molecular formula C19H19N3O4 and a molecular weight of 353.37 g/mol.

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.
