Chemical Structure
Description
3′-Carboxy-4′-fluoro[1,1′-biphenyl]-3-acetic acid (CAS 1375068-82-8) is a high-purity analytical reference standard with the molecular formula C15H11FO4 and a molecular weight of 274.24 g/mol.
The molecular framework of 3′-Carboxy-4′-fluoro[1,1′-biphenyl]-3-acetic acid (C15H11FO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3′-Carboxy-4′-fluoro[1,1′-biphenyl]-3-acetic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
