Chemical Structure
Description
3-(2-(4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazin-1-yl)ethoxy)benzaldehyde (CAS 338409-15-7), molecular formula C19H19ClF3N3O2 and molecular weight 413.82 g/mol, is a CATO reference standard with documented purity and traceability.
3-(2-(4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)piperazin-1-yl)ethoxy)benzaldehyde (C19H19ClF3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
