Description

Compared with other compounds in its class, the molecular weight of 241.22 g/mol gives 4'-Cyano-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4'-Cyano-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid (CAS 1261920-60-8), molecular formula C14H8FNO2 and molecular weight 241.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H8FNO2, 4'-Cyano-5-fluoro-[1,1'-biphenyl]-2-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 241.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
