Chemical Structure

Ethyl 3-(trifluoromethyl)-1,2,4-oxadiazole-5-carboxylate CAS 1245643-72-4 chemical structure

Description

The occurrence of Ethyl 3-(trifluoromethyl)-1,2,4-oxadiazole-5-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 3-(trifluoromethyl)-1,2,4-oxadiazole-5-carboxylate (CAS 1245643-72-4), a certified reference material (molecular formula C6H5F3N2O3, MW 210.11 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Ethyl 3-(trifluoromethyl)-1,2,4-oxadiazole-5-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
