Description
2-(3,4-dichlorophenyl)-1-[4-(4-methoxyphenyl)piperazino]-1-ethanone 746633-16-9 KS-00003DU8 (CAS 746633-16-9), molecular formula C19H20Cl2N2O2 and molecular weight 379.28 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3,4-dichlorophenyl)-1-[4-(4-methoxyphenyl)piperazino]-1-ethanone 746633-16-9 KS-00003DU8 (C19H20Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
