CATO supplies 3-((2-Oxo-2-phenylethyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (CAS 891125-31-8), a certified reference material (molecular formula C16H16N4O2S, MW 328.39 g/mol) for analytical method development and quality control.
The molecular framework of 3-((2-Oxo-2-phenylethyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (C16H16N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
