Chemical Structure
Description
2-Cyano-3-(2,4-dimethoxyphenyl)-N-(4-ethylphenyl)propanamide (C20H22N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2-Cyano-3-(2,4-dimethoxyphenyl)-N-(4-ethylphenyl)propanamide (CAS 1261014-69-0), a certified reference material (molecular formula C20H22N2O3, MW 338.40 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.
