2,5-Dichloro-3-(3,4-dimethylphenyl)propiophenone CAS 898779-79-8

Description

Compared with other compounds in its class, the molecular weight of 307.21 g/mol gives 2,5-Dichloro-3-(3,4-dimethylphenyl)propiophenone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,5-Dichloro-3-(3,4-dimethylphenyl)propiophenone (CAS 898779-79-8), molecular formula C17H16Cl2O and molecular weight 307.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,5-Dichloro-3-(3,4-dimethylphenyl)propiophenone (C17H16Cl2O) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
