Based on its molecular formula C14H25NO2, 441-38-3 Benzoin oxime Benzoin, oxime Benzoin, oxime (VAN) (8CI) Benzoinoxime Ethanone, 2-hydroxy-1,2-diphenyl-, oxime Ethanone, 2-hydroxy-1,2-diphenyl-, oxime (alpha isomer) (E)-(1)-2-Hydroxy-1,2-diphenylethan-1-one oxime 1-08-00-00573 (Beilstein Handbook Reference) AI3-14935 AI3-52537 Benzoin, alpha-oxime Benzoinoxim [Czech] BRN 2051941 Cupron [Czech] Cuprone EINECS 207-127-2 EINECS 227-665-1 NSC 659 USAF FA-5 Benzoinoxim Cupron alpha-Benzoin oxime contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
