Chemical Structure
Description
The occurrence of 2-(4-Ethoxy-2,3-difluorophenyl)acetic acid 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.
2-(4-Ethoxy-2,3-difluorophenyl)acetic acid (CAS 1017779-62-2) is a high-purity analytical reference standard with the molecular formula C10H10F2O3 and a molecular weight of 216.18 g/mol.
2-(4-Ethoxy-2,3-difluorophenyl)acetic acid (C10H10F2O3) 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.
