Chemical Structure
Description
2-(4-(2-Hydroxyethyl)-3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)-6-(trifluoromethyl)pyrimidin-4(3H)-one (C11H11F3N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
