4-(2-AMinoethyl)-5-[4-(dimethylamino)phenyl]-1,2-dihydro-3h-pyrazol-3-one (CAS 881040-92-2), molecular formula C13H18N4O and molecular weight 246.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-AMinoethyl)-5-[4-(dimethylamino)phenyl]-1,2-dihydro-3h-pyrazol-3-one (C13H18N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
