Chemical Structure
Description
The occurrence of 4-(3-Fluoro-4-methylphenyl)benzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(3-Fluoro-4-methylphenyl)benzonitrile (CAS 1352318-56-9), molecular formula C14H10FN and molecular weight 211.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H10FN, 4-(3-Fluoro-4-methylphenyl)benzonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 211.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
