4-Amino-N-(4-((2-amino-6-methylpyrimidin-4-yl)amino)phenyl)benzamide (CAS 1020150-22-4), molecular formula C18H18N6O and molecular weight 334.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-N-(4-((2-amino-6-methylpyrimidin-4-yl)amino)phenyl)benzamide (C18H18N6O) 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 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).
As a certified reference material (CRM), 4-Amino-N-(4-((2-amino-6-methylpyrimidin-4-yl)amino)phenyl)benzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
