4-(Methylsulfanyl)-2-oxo-6-phenyl-1-(prop-2-en-1-yl)-1,2-dihydropyridine-3-carbonitrile CAS 478042-85-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Methylsulfanyl)-2-oxo-6-phenyl-1-(prop-2-en-1-yl)-1,2-dihydropyridine-3-carbonitrile.

CATO supplies 4-(Methylsulfanyl)-2-oxo-6-phenyl-1-(prop-2-en-1-yl)-1,2-dihydropyridine-3-carbonitrile (CAS 478042-85-2), a certified reference material (molecular formula C16H14N2OS, MW 282.36 g/mol) for analytical method development and quality control.

The molecular framework of 4-(Methylsulfanyl)-2-oxo-6-phenyl-1-(prop-2-en-1-yl)-1,2-dihydropyridine-3-carbonitrile (C16H14N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
