Description

Compared with other compounds in its class, the molecular weight of 234.20 g/mol gives 3,4'-Difluoro-[1,1'-biphenyl]-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,4'-Difluoro-[1,1'-biphenyl]-4-carboxylic acid (CAS 786685-86-7), a certified reference material (molecular formula C13H8F2O2, MW 234.20 g/mol) for analytical method development and quality control.

Structurally, 3,4'-Difluoro-[1,1'-biphenyl]-4-carboxylic acid (C13H8F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 234.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
