Chemical Structure
Description
4-Ethyl-6-hydroxy-2-methylpyrimidine-5-carbonitrile (CAS 64929-23-3) is a high-purity analytical reference standard with the molecular formula C8H9N3O and a molecular weight of 163.18 g/mol.
The molecular framework of 4-Ethyl-6-hydroxy-2-methylpyrimidine-5-carbonitrile (C8H9N3O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-Ethyl-6-hydroxy-2-methylpyrimidine-5-carbonitrile 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.
