Chemical Structure

2,6-dichloro-1,5-dihydropyrimido[5,4-d]pyrimidine-4,8-dione 50492-71-2 CAS 50492-71-2 chemical structure

Description

The molecular framework of 2,6-dichloro-1,5-dihydropyrimido[5,4-d]pyrimidine-4,8-dione 50492-71-2 (C6H2Cl2N4O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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).

2,6-dichloro-1,5-dihydropyrimido[5,4-d]pyrimidine-4,8-dione 50492-71-2 (CAS 50492-71-2) is a high-purity analytical reference standard with the molecular formula C6H2Cl2N4O2 and a molecular weight of 233.01 g/mol.
