Chemical Structure
Description
The occurrence of 4'-cyano-3-(3,5-dimethylphenyl)propiophenone is closely related to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4'-cyano-3-(3,5-dimethylphenyl)propiophenone (CAS 898780-58-0), a certified reference material (molecular formula C17H17FO, MW 256.31 g/mol) for analytical method development and quality control.
The molecular framework of 4'-cyano-3-(3,5-dimethylphenyl)propiophenone (C17H17FO) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
