(E)-N'-((3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)methylene)benzohydrazide (CAS 956211-76-0), molecular formula C29H22N4O and molecular weight 442.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-N'-((3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)methylene)benzohydrazide (C29H22N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 442.51 g/mol, it falls into the moderately-high-molecular-weight range. 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).
As a certified reference material (CRM), (E)-N'-((3-([1,1'-biphenyl]-4-yl)-1-phenyl-1H-pyrazol-4-yl)methylene)benzohydrazide 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.
