Chemical Structure
Description
The occurrence of 3-(3-Fluoro-4-hydroxyphenyl)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.
3-(3-Fluoro-4-hydroxyphenyl)propanoic acid (CAS 69888-91-1), molecular formula C9H9FO3 and molecular weight 184.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(3-Fluoro-4-hydroxyphenyl)propanoic acid (C9H9FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 184.16 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
