Chemical Structure
Description
3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid (C13H11FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic acid (CAS 1261959-24-3) is a high-purity analytical reference standard with the molecular formula C13H11FO and a molecular weight of 202.22 g/mol.
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'-Fluoro-2,4'-dimethyl-[1,1'-biphenyl]-4-carboxylic 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.
