Description
As a certified reference material (CRM), 5-(Pyridin-2-yl)pyrimidin-4(3H)-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.
5-(Pyridin-2-yl)pyrimidin-4(3H)-one (CAS 22433-74-5) is a high-purity analytical reference standard with the molecular formula C9H7N3O and a molecular weight of 173.17 g/mol.
The molecular framework of 5-(Pyridin-2-yl)pyrimidin-4(3H)-one (C9H7N3O) 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.
