5-(Chloromethyl)-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(4H)-one (CAS 1227417-79-9), molecular formula C12H9ClN4O and molecular weight 260.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Chloromethyl)-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(4H)-one (C12H9ClN4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
