Chemical Structure

3-(3,5-Dimethylphenyl)benzonitrile CAS 713079-19-7 chemical structure

Description

3-(3,5-Dimethylphenyl)benzonitrile (CAS 713079-19-7) is a high-purity analytical reference standard with the molecular formula C15H13N and a molecular weight of 207.27 g/mol.

Based on its molecular formula C15H13N, 3-(3,5-Dimethylphenyl)benzonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
