3-Fluoro-[1,1'-biphenyl]-2-carboxylic acid CAS 1841-56-1

Description

Compared with other compounds in its class, the molecular weight of 216.21 g/mol gives 3-Fluoro-[1,1'-biphenyl]-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Fluoro-[1,1'-biphenyl]-2-carboxylic acid (CAS 1841-56-1), molecular formula C13H9FO2 and molecular weight 216.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3-Fluoro-[1,1'-biphenyl]-2-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-Fluoro-[1,1'-biphenyl]-2-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.
