Chemical Structure

Cyclohexyl 2-(2,5-dimethylphenyl)ethyl ketone CAS 898754-22-8 chemical structure

Description

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.

Cyclohexyl 2-(2,5-dimethylphenyl)ethyl ketone (CAS 898754-22-8) is a high-purity analytical reference standard with the molecular formula C17H24O and a molecular weight of 244.37 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Cyclohexyl 2-(2,5-dimethylphenyl)ethyl ketone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
