Compared with other compounds in its class, the molecular weight of 204.23 g/mol gives 4-(3-Cyanophenyl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(3-Cyanophenyl)benzonitrile (CAS 42289-54-3) is a high-purity analytical reference standard with the molecular formula C14H8N2 and a molecular weight of 204.23 g/mol.
Structurally, 4-(3-Cyanophenyl)benzonitrile (C14H8N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 204.23 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).
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.
