Chemical Structure
Description
Diethyl 2-(2-oxo-2-(4-(3-(trifluoromethyl)phenyl)piperazin-1-yl)ethyl)malonate (CAS 633318-79-3), molecular formula C20H25F3N2O5 and molecular weight 430.42 g/mol, is a CATO reference standard with documented purity and traceability.
Diethyl 2-(2-oxo-2-(4-(3-(trifluoromethyl)phenyl)piperazin-1-yl)ethyl)malonate (C20H25F3N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
CATO manufactures Diethyl 2-(2-oxo-2-(4-(3-(trifluoromethyl)phenyl)piperazin-1-yl)ethyl)malonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
