Chemical Structure

Ethyl 5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](methyl)amino}-4,6-dioxo-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate CAS 321433-48-1 chemical structure

Description

Structurally, Ethyl 5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl](methyl)amino}-4,6-dioxo-3aH,4H,5H,6H,6aH-pyrrolo[3,4-d][1,2]oxazole-3-carboxylate (C15H12ClF3N4O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 420.73 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
