Chemical Structure

3,5-Dimethyl-3-(2,4-dimethylphenyl)propiophenone CAS 898794-17-7 chemical structure

Description

3,5-Dimethyl-3-(2,4-dimethylphenyl)propiophenone (CAS 898794-17-7) is a high-purity analytical reference standard with the molecular formula C19H22O and a molecular weight of 266.38 g/mol.

3,5-Dimethyl-3-(2,4-dimethylphenyl)propiophenone (C19H22O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
