Chemical Structure

2-Fluoro-biphenyl-3-carboxylic acid CAS 177942-40-4 chemical structure

Description

The occurrence of 2-Fluoro-biphenyl-3-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Fluoro-biphenyl-3-carboxylic acid (CAS 177942-40-4) is a high-purity analytical reference standard with the molecular formula C13H9FO2 and a molecular weight of 216.21 g/mol.

2-Fluoro-biphenyl-3-carboxylic acid (C13H9FO2) contains a carboxylic acid group, 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-Fluoro-biphenyl-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
