1-Butyl-2-[(E)-[(3-methylphenyl)methylidene]amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile (CAS 478032-82-5), molecular formula C29H27N3 and molecular weight 417.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Butyl-2-[(E)-[(3-methylphenyl)methylidene]amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.54 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.
As a certified reference material (CRM), 1-Butyl-2-[(E)-[(3-methylphenyl)methylidene]amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile 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.
