1-Isopropyl-3-methyl-6-((5-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidine-5-carboxylic acid (CAS 733810-92-9) is a high-purity analytical reference standard with the molecular formula C17H17F3N4O4S and a molecular weight of 430.40 g/mol.
Based on its molecular formula C17H17F3N4O4S, 1-Isopropyl-3-methyl-6-((5-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl)methyl)-2,4-dioxo-1,2,3,4-tetrahydrothieno[2,3-d]pyrimidine-5-carboxylic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 430.40 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.
