Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 446.59 g/mol gives 1-Butyl-2-[(E)-{[4-(dimethylamino)phenyl]methylidene}amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Butyl-2-[(E)-{[4-(dimethylamino)phenyl]methylidene}amino]-4,5-diphenyl-1H-pyrrole-3-carbonitrile (CAS 478032-87-0), a certified reference material (molecular formula C30H30N4, MW 446.59 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Butyl-2-[(E)-{[4-(dimethylamino)phenyl]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 446.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
