Chemical Structure

(E)-1-(4-(1H-pyrrol-1-yl)phenyl)-3-(2-ethoxyphenyl)prop-2-en-1-one CAS 551930-67-7 chemical structure

Description

CATO supplies (E)-1-(4-(1H-pyrrol-1-yl)phenyl)-3-(2-ethoxyphenyl)prop-2-en-1-one (CAS 551930-67-7), a certified reference material (molecular formula C21H19NO2, MW 317.38 g/mol) for analytical method development and quality control.

(E)-1-(4-(1H-pyrrol-1-yl)phenyl)-3-(2-ethoxyphenyl)prop-2-en-1-one (C21H19NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).

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.
