Compared with other compounds in its class, the molecular weight of 295.34 g/mol gives 6-Methyl-2-{3-methyl-5-[(4-methylphenyl)amino]-1H-pyrazol-1-yl}-1,4-dihydropyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Methyl-2-{3-methyl-5-[(4-methylphenyl)amino]-1H-pyrazol-1-yl}-1,4-dihydropyrimidin-4-one (CAS 882231-37-0), a certified reference material (molecular formula C16H17N5O, MW 295.34 g/mol) for analytical method development and quality control.
The molecular framework of 6-Methyl-2-{3-methyl-5-[(4-methylphenyl)amino]-1H-pyrazol-1-yl}-1,4-dihydropyrimidin-4-one (C16H17N5O) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Methyl-2-{3-methyl-5-[(4-methylphenyl)amino]-1H-pyrazol-1-yl}-1,4-dihydropyrimidin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
