Chemical Structure

1-(Propan-2-yl)-3-(trifluoromethyl)-1h-pyrazole-5-carbonyl chloride CAS 129768-32-7 chemical structure

Description

Based on its molecular formula C8H8ClF3N2O, 1-(Propan-2-yl)-3-(trifluoromethyl)-1h-pyrazole-5-carbonyl chloride 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 240.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
