Compared with other compounds in its class, the molecular weight of 227.69 g/mol gives 4-(3-Chloro-4-methylphenyl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(3-Chloro-4-methylphenyl)benzonitrile (CAS 1352318-49-0) is a high-purity analytical reference standard with the molecular formula C14H10ClN and a molecular weight of 227.69 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-(3-Chloro-4-methylphenyl)benzonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 227.69 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.
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.
