2,4-Diamino-6-chloro-5-nitropyrimidine (CAS 6036-64-2) is a high-purity analytical reference standard with the molecular formula C4H4ClN5O2 and a molecular weight of 189.56 g/mol.
2,4-Diamino-6-chloro-5-nitropyrimidine (C4H4ClN5O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
