Chemical Structure
Description
The molecular framework of 2,5-Dimethyl-3-(3,5-dimethylphenyl)propiophenone (C19H22O) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).
2,5-Dimethyl-3-(3,5-dimethylphenyl)propiophenone (CAS 898780-66-0), molecular formula C19H22O and molecular weight 266.38 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2,5-Dimethyl-3-(3,5-dimethylphenyl)propiophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
