Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-{[(4-chlorophenyl)methyl]sulfanyl}-5-methoxy-4-(phenylsulfanyl)pyrimidine (CAS 338423-06-6), molecular formula C18H15ClN2OS2 and molecular weight 374.91 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H15ClN2OS2, 2-{[(4-chlorophenyl)methyl]sulfanyl}-5-methoxy-4-(phenylsulfanyl)pyrimidine contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 374.91 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.
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.
