1-(2,5-Dimethylphenyl)-3-(2,6-dimethylphenyl)propan-1-one CAS 898754-86-4

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 1-(2,5-Dimethylphenyl)-3-(2,6-dimethylphenyl)propan-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.38 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).

1-(2,5-Dimethylphenyl)-3-(2,6-dimethylphenyl)propan-1-one (CAS 898754-86-4), molecular formula C19H22O and molecular weight 266.38 g/mol, is a CATO reference standard with documented purity and traceability.

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.
