Chemical Structure
Description
(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-(trifluoromethyl)phenyl)methanone (CAS 898773-32-5) is a high-purity analytical reference standard with the molecular formula C15H11F3O3S and a molecular weight of 328.31 g/mol.
Based on its molecular formula C15H11F3O3S, (5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(4-(trifluoromethyl)phenyl)methanone contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 328.31 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
