The molecular framework of N-(1,2-Diacetyl-3-oxo-2,3-dihydro-1H-indazol-6-yl)acetamide (C13H13N3O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
N-(1,2-Diacetyl-3-oxo-2,3-dihydro-1H-indazol-6-yl)acetamide (CAS 61346-25-6), molecular formula C13H13N3O4 and molecular weight 275.26 g/mol, is a CATO reference standard with documented purity and traceability.
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-(1,2-Diacetyl-3-oxo-2,3-dihydro-1H-indazol-6-yl)acetamide 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.
