4-Chloro-6-(3,4-dimethoxyphenyl)pyrimidine (CAS 103555-31-3), molecular formula C12H11ClN2O2 and molecular weight 250.68 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-6-(3,4-dimethoxyphenyl)pyrimidine (C12H11ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
