1-(4-(4-Chloro-2-nitrophenyl)piperazin-1-yl)ethan-1-one (CAS 329922-78-3), molecular formula C12H14ClN3O3 and molecular weight 283.71 g/mol, is a CATO reference standard with documented purity and traceability.
1-(4-(4-Chloro-2-nitrophenyl)piperazin-1-yl)ethan-1-one (C12H14ClN3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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.
