4-Ethyl-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione CAS 865659-97-8

Description

4-Ethyl-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 865659-97-8) is a high-purity analytical reference standard with the molecular formula C11H10F3N5S2 and a molecular weight of 333.36 g/mol.

Based on its molecular formula C11H10F3N5S2, 4-Ethyl-5-(1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazol-5-yl)-2,4-dihydro-3H-1,2,4-triazole-3-thione contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 333.36 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).
