N-(2-Aminophenyl)-4-((4,6-difluoro-2H-indazol-2-yl)methyl)benzamide (CAS 920315-04-4), molecular formula C21H16F2N4O and molecular weight 378.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Aminophenyl)-4-((4,6-difluoro-2H-indazol-2-yl)methyl)benzamide (C21H16F2N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.

As a certified reference material (CRM), N-(2-Aminophenyl)-4-((4,6-difluoro-2H-indazol-2-yl)methyl)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.
