Chemical Structure
Description
The molecular framework of 1-Ethylpyrido[2,3-d]pyrimidine-2,4,7(1H,3H,8H)-trione (C9H9N3O3) is characterized by an amino-acid-derived structure, 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).
1-Ethylpyrido[2,3-d]pyrimidine-2,4,7(1H,3H,8H)-trione (CAS 1707375-88-9), molecular formula C9H9N3O3 and molecular weight 207.19 g/mol, is a CATO reference standard with documented purity and traceability.
