3-((2,5-Dimethylbenzyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (CAS 891124-28-0), molecular formula C17H20N4OS and molecular weight 328.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-((2,5-Dimethylbenzyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one (C17H20N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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.
As a certified reference material (CRM), 3-((2,5-Dimethylbenzyl)thio)-5-propyl-[1,2,4]triazolo[4,3-a]pyrimidin-7(8H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
