Chemical Structure

(2E)-3-[5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-1-(pyridin-2-yl)prop-2-en-1-one CAS 477708-82-0 chemical structure

Description

Based on its molecular formula C13H9ClF3N3O, (2E)-3-[5-Chloro-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-yl]-1-(pyridin-2-yl)prop-2-en-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.68 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.
