Chemical Structure
Description
4′-Fluoro[1,1′-biphenyl]-3-carbonitrile (CAS 10540-33-7) is a high-purity analytical reference standard with the molecular formula C13H8FN and a molecular weight of 197.21 g/mol.
4′-Fluoro[1,1′-biphenyl]-3-carbonitrile (C13H8FN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
