2-(2-Hydroxyethyl)benzonitrile CAS 42247-74-5

Description

Compared with other compounds in its class, the molecular weight of 147.17 g/mol gives 2-(2-Hydroxyethyl)benzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Hydroxyethyl)benzonitrile (CAS 42247-74-5) is a high-purity analytical reference standard with the molecular formula C9H9NO and a molecular weight of 147.17 g/mol.

The molecular framework of 2-(2-Hydroxyethyl)benzonitrile (C9H9NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
