2-(3,4-Dichlorophenyl)-4-methyl-6-(phenylamino)quinazoline-5,8-dione (CAS 61462-71-3), molecular formula C21H13Cl2N3O2 and molecular weight 410.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3,4-Dichlorophenyl)-4-methyl-6-(phenylamino)quinazoline-5,8-dione (C21H13Cl2N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
