2-(4-chlorophenyl)pentanoic acid (CAS 42222-72-0), molecular formula C11H13ClO2 and molecular weight 212.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-chlorophenyl)pentanoic acid (C11H13ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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.
