Compared with other compounds in its class, the molecular weight of 152.11 g/mol gives [1,2,4]Triazolo[1,5-a]pyrimidine-5,7(1H,6H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
[1,2,4]Triazolo[1,5-a]pyrimidine-5,7(1H,6H)-dione (CAS 211733-06-1) is a high-purity analytical reference standard with the molecular formula C5H4N4O2 and a molecular weight of 152.11 g/mol.
The molecular framework of [1,2,4]Triazolo[1,5-a]pyrimidine-5,7(1H,6H)-dione (C5H4N4O2) 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).
