Chemical Structure

3-Ethynyl-2-cyclohexenone CAS 124267-26-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 120.15 g/mol gives 3-Ethynyl-2-cyclohexenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Ethynyl-2-cyclohexenone (CAS 124267-26-1), a certified reference material (molecular formula C8H8O, MW 120.15 g/mol) for analytical method development and quality control.

Structurally, 3-Ethynyl-2-cyclohexenone (C8H8O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 120.15 g/mol, it falls into the low-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.
