Chemical Structure
Description
Structurally, 1-((5-(3-Methoxyphenyl)-1,2,4-oxadiazol-3-yl)methyl)-5-(3-(thiophen-3-yl)-1,2,4-oxadiazol-5-yl)pyridin-2(1H)-one (C21H15N5O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 433.44 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).
