Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 200.18 g/mol gives 2-(3,5-Difluorophenyl)butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3,5-Difluorophenyl)butanoic acid (CAS 1225522-69-9) is a high-purity analytical reference standard with the molecular formula C10H10F2O2 and a molecular weight of 200.18 g/mol.
The molecular framework of 2-(3,5-Difluorophenyl)butanoic acid (C10H10F2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
