3-(2-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione CAS 578720-77-1

Description

Structurally, 3-(2-Fluorophenyl)-4-((4-(methylthio)benzylidene)amino)-1H-1,2,4-triazole-5(4H)-thione (C16H13FN4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 344.43 g/mol, it falls into the moderately-high-molecular-weight range. 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).
