Chemical Structure

1,4-bis(2,2,2-trifluoroethyl) but-2-enedioate 352-28-3 Bis(2,2,2-trifluoroethyl) (2Z)-but-2-ene-1,4-dioate Maleic acid bis(2,2,2-trifluoroethyl)ester CAS 352-28-3 chemical structure

Description

Structurally, 1,4-bis(2,2,2-trifluoroethyl) but-2-enedioate 352-28-3 Bis(2,2,2-trifluoroethyl) (2Z)-but-2-ene-1,4-dioate Maleic acid bis(2,2,2-trifluoroethyl)ester (C8H6F6O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 280.12 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
