As a certified reference material (CRM), 4-(5-Isopropyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride 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.
4-(5-Isopropyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride (CAS 1177093-06-9), molecular formula C13H18N6OHCl and molecular weight 310.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(5-Isopropyl-1,2,4-oxadiazol-3-yl)-2-piperazin-1-ylpyrimidine dihydrochloride (C13H18N6OHCl) 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. 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.
