Chemical Structure
Description
Structurally, 5-Methyl-1-((5-(trifluoromethyl)-1,3,4-oxadiazol-2-yl)methyl)pyrimidine-2,4(1H,3H)-dione (C9H7F3N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 276.17 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).
