Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[(4-Methylphenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile.
CATO supplies 1-[(4-Methylphenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile (CAS 339108-83-7), a certified reference material (molecular formula C20H16N2O, MW 300.35 g/mol) for analytical method development and quality control.
Based on its molecular formula C20H16N2O, 1-[(4-Methylphenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1-[(4-Methylphenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-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.
