Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one.
5-Phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (CAS 34102-79-9), molecular formula C11H8N4O and molecular weight 212.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (C11H8N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
