Chemical Structure
Description
156301-63-2 2-Methyl-4-[4-(trifluoromethyl)phenyl]but-3-yn-2-ol DTXSID40468084 (C12H11F3O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
