Methyl 2-[5-cyano-3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl]-3-thiophenecarboxylate CAS 343374-94-7 chemical structure

Description

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 2-[5-cyano-3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl]-3-thiophenecarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Methyl 2-[5-cyano-3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl]-3-thiophenecarboxylate (CAS 343374-94-7), molecular formula C19H15N3O5S and molecular weight 397.40 g/mol, is a CATO reference standard with documented purity and traceability.
