Chemical Structure

1,2,2-triphenylethan-1-one CAS 1733-63-7 chemical structure

Description

Structurally, 1,2,2-triphenylethan-1-one (C20H16O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 272.34 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).

1,2,2-triphenylethan-1-one (CAS 1733-63-7) is a high-purity analytical reference standard with the molecular formula C20H16O and a molecular weight of 272.34 g/mol.

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.
