4-[(4-Fluorophenyl)sulfanyl]butanoic acid (CAS 18850-56-1) is a high-purity analytical reference standard with the molecular formula C10H11FO2S and a molecular weight of 214.26 g/mol.
The molecular framework of 4-[(4-Fluorophenyl)sulfanyl]butanoic acid (C10H11FO2S) is characterized by a sulfone group, 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.
