Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-1-butyl-2-((2-chlorobenzylidene)amino)-4,5-diphenyl-1H-pyrrole-3-carbonitrile.
(E)-1-butyl-2-((2-chlorobenzylidene)amino)-4,5-diphenyl-1H-pyrrole-3-carbonitrile (CAS 478032-80-3) is a high-purity analytical reference standard with the molecular formula C28H24ClN3 and a molecular weight of 437.96 g/mol.
The molecular framework of (E)-1-butyl-2-((2-chlorobenzylidene)amino)-4,5-diphenyl-1H-pyrrole-3-carbonitrile (C28H24ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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.
