Chemical Structure

(2E)-3-(2,6-Difluoro-4-methoxyphenyl)-2-propenoic Acid Ethyl Ester CAS 858114-78-0 chemical structure

Description

The occurrence of (2E)-3-(2,6-Difluoro-4-methoxyphenyl)-2-propenoic Acid Ethyl Ester is closely related to 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.

(2E)-3-(2,6-Difluoro-4-methoxyphenyl)-2-propenoic Acid Ethyl Ester (CAS 858114-78-0) is a high-purity analytical reference standard with the molecular formula C12H12F2O3 and a molecular weight of 242.22 g/mol.

(2E)-3-(2,6-Difluoro-4-methoxyphenyl)-2-propenoic Acid Ethyl Ester (C12H12F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
