Description
As a certified reference material (CRM), 1-Butyl-2-[(E)-[(3-methoxyphenyl)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.
1-Butyl-2-[(E)-[(3-methoxyphenyl)methylidene]amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile (CAS 477887-45-9) is a high-purity analytical reference standard with the molecular formula C29H27N3O and a molecular weight of 433.54 g/mol.
The molecular framework of 1-Butyl-2-[(E)-[(3-methoxyphenyl)methylidene]amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile (C29H27N3O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
