4-Hydroxy-2-oxo-N'-[(1E)-(2-phenoxyphenyl)methylidene]-1-azatricyclo[7.3.1.0^{5,13}]trideca-3,5(13),6,8-tetraene-3-carbohydrazide (CAS 477868-72-7) is a high-purity analytical reference standard with the molecular formula C26H21N3O4 and a molecular weight of 439.46 g/mol.

The molecular framework of 4-Hydroxy-2-oxo-N'-[(1E)-(2-phenoxyphenyl)methylidene]-1-azatricyclo[7.3.1.0^{5,13}]trideca-3,5(13),6,8-tetraene-3-carbohydrazide (C26H21N3O4) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
