Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-7-styryl-[1,2,4]triazolo[1,5-a]pyrimidine (CAS 91823-31-3), molecular formula C13H10N4 and molecular weight 222.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-7-styryl-[1,2,4]triazolo[1,5-a]pyrimidine (C13H10N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (E)-7-styryl-[1,2,4]triazolo[1,5-a]pyrimidine 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.
