N'-[(1E)-(3-Chlorophenyl)methylidene]-4-hydroxy-2-oxo-1-azatricyclo[7.3.1.0^{5,13}]trideca-3,5(13),6,8-tetraene-3-carbohydrazide (CAS 477859-84-0) is a high-purity analytical reference standard with the molecular formula C20H16ClN3O3 and a molecular weight of 381.81 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N'-[(1E)-(3-Chlorophenyl)methylidene]-4-hydroxy-2-oxo-1-azatricyclo[7.3.1.0^{5,13}]trideca-3,5(13),6,8-tetraene-3-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 381.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
