As a certified reference material (CRM), 1-[(4-Methylphenyl)methyl]-4-(methylsulfanyl)-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.

CATO supplies 1-[(4-Methylphenyl)methyl]-4-(methylsulfanyl)-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile (CAS 478042-81-8), a certified reference material (molecular formula C21H18N2OS, MW 346.45 g/mol) for analytical method development and quality control.

Structurally, 1-[(4-Methylphenyl)methyl]-4-(methylsulfanyl)-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile (C21H18N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 346.45 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
