Chemical Structure
Description
The molecular framework of Ethyl 2-(3-(3,5-dimethylphenyl)propanoyl)benzoate (C20H22O3) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Ethyl 2-(3-(3,5-dimethylphenyl)propanoyl)benzoate (CAS 898780-32-0), a certified reference material (molecular formula C20H22O3, MW 310.39 g/mol) for analytical method development and quality control.
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.
