(5Z)-2-(Hydroxyamino)-5-{[2-(trifluoromethyl)phenyl]methylidene}-4,5-dihydro-1,3-thiazol-4-one CAS 866040-89-3

Description

Structurally, (5Z)-2-(Hydroxyamino)-5-{[2-(trifluoromethyl)phenyl]methylidene}-4,5-dihydro-1,3-thiazol-4-one (C11H7F3N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 288.25 g/mol, it falls into the medium-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).
