Chemical Structure
Description
The molecular framework of n-Hydroxy-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-5-carboxamide (C5H5N3O4) is characterized by a carbohydrate-derived structure, an amide group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
