Chemical Structure
Description
(Z)-N-(1-Bromo-1-(4-chlorophenyl)-3-oxo-3-(piperidin-1-yl)prop-1-en-2-yl)benzamide (C21H20BrClN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(Z)-N-(1-Bromo-1-(4-chlorophenyl)-3-oxo-3-(piperidin-1-yl)prop-1-en-2-yl)benzamide (CAS 1800044-61-4), molecular formula C21H20BrClN2O2 and molecular weight 447.75 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
