Chemical Structure
Description
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.
(E)-4,4-dimethyl-2-(methylthio)-6-(4-(trifluoromethyl)styryl)-1,4-dihydropyrimidine (CAS 303148-57-4) is a high-purity analytical reference standard with the molecular formula C16H17F3N2S and a molecular weight of 326.38 g/mol.
(E)-4,4-dimethyl-2-(methylthio)-6-(4-(trifluoromethyl)styryl)-1,4-dihydropyrimidine (C16H17F3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
