N7-benzyl-N4-(3-ethynylphenyl)-6-nitroquinazoline-4,7-diamine (CAS CATO-C3D-262421) is a high-purity analytical reference standard with the molecular formula C23H17N5O2 and a molecular weight of 395.41 g/mol.
The molecular framework of N7-benzyl-N4-(3-ethynylphenyl)-6-nitroquinazoline-4,7-diamine (C23H17N5O2) 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.
