Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-({[(4-chlorophenyl)methyl]sulfanyl}methyl)-6-[(4-methylphenyl)sulfanyl]-2-(pyridin-2-yl)pyrimidine.
CATO supplies 4-({[(4-chlorophenyl)methyl]sulfanyl}methyl)-6-[(4-methylphenyl)sulfanyl]-2-(pyridin-2-yl)pyrimidine (CAS 338960-89-7), a certified reference material (molecular formula C24H20ClN3S2, MW 450.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C24H20ClN3S2, 4-({[(4-chlorophenyl)methyl]sulfanyl}methyl)-6-[(4-methylphenyl)sulfanyl]-2-(pyridin-2-yl)pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 450.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
