Chemical Structure
Description
The molecular framework of 7-Oxo-7,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylic acid 1246668-87-0 (C8H5N3O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
