Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Ethyl-1-isobutyl-6-(phenylthio)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 136160-39-9), molecular formula C16H20N2OS2 and molecular weight 320.47 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H20N2OS2, 5-Ethyl-1-isobutyl-6-(phenylthio)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 320.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
