(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(3,5-dichlorophenyl)methanone (CAS 898778-96-6) is a high-purity analytical reference standard with the molecular formula C14H10Cl2O3S and a molecular weight of 329.20 g/mol.
(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)(3,5-dichlorophenyl)methanone (C14H10Cl2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
