Chemical Structure
Description
The occurrence of 2-(2,4-Difluorophenoxy)propanoic 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.
CATO supplies 2-(2,4-Difluorophenoxy)propanoic acid (CAS 52043-21-7), a certified reference material (molecular formula C9H8F2O3, MW 202.15 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H8F2O3, 2-(2,4-Difluorophenoxy)propanoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
