5,7-dichloro-2-methyl-3H,4H-pyrrolo[2,1-f][1,2,4]triazin-4-one (CAS 1824632-67-8), molecular formula C7H11Cl2N3O and molecular weight 224.09 g/mol, is a CATO reference standard with documented purity and traceability.
5,7-dichloro-2-methyl-3H,4H-pyrrolo[2,1-f][1,2,4]triazin-4-one (C7H11Cl2N3O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
