2,3-Dimethyl-3-(4-methoxyphenyl)propiophenone CAS 898775-80-9

Description

Compared with other compounds in its class, the molecular weight of 268.35 g/mol gives 2,3-Dimethyl-3-(4-methoxyphenyl)propiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3-Dimethyl-3-(4-methoxyphenyl)propiophenone (CAS 898775-80-9) is a high-purity analytical reference standard with the molecular formula C18H20O2 and a molecular weight of 268.35 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 2,3-Dimethyl-3-(4-methoxyphenyl)propiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
