5-(Benzylamino)-N-ethyl-1-phenyl-1H-pyrazole-4-carboxamide (CAS 136139-67-8), molecular formula C19H20N4O and molecular weight 320.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(Benzylamino)-N-ethyl-1-phenyl-1H-pyrazole-4-carboxamide (C19H20N4O) is characterized by a steroid core, 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 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.
