(E)-1-butyl-4,5-diphenyl-2-((thiophen-2-ylmethylene)amino)-1H-pyrrole-3-carbonitrile CAS 477887-47-1

Description

CATO supplies (E)-1-butyl-4,5-diphenyl-2-((thiophen-2-ylmethylene)amino)-1H-pyrrole-3-carbonitrile (CAS 477887-47-1), a certified reference material (molecular formula C26H23N3S, MW 409.55 g/mol) for analytical method development and quality control.

The molecular framework of (E)-1-butyl-4,5-diphenyl-2-((thiophen-2-ylmethylene)amino)-1H-pyrrole-3-carbonitrile (C26H23N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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.

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.
