Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2E)-3-(Dimethylamino)-2-[(E)-3-[4-(propan-2-yl)phenoxy]benzoyl]prop-2-enenitrile (CAS 1164465-41-1), molecular formula C21H22N2O2 and molecular weight 334.41 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-3-(Dimethylamino)-2-[(E)-3-[4-(propan-2-yl)phenoxy]benzoyl]prop-2-enenitrile (C21H22N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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.
