(1E)-1-[1-(4-Bromophenyl)-1H-pyrrol-3-yl]-N-(3,4-dichlorophenyl)methanimine CAS 691870-07-2 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 (1E)-1-[1-(4-Bromophenyl)-1H-pyrrol-3-yl]-N-(3,4-dichlorophenyl)methanimine.

CATO supplies (1E)-1-[1-(4-Bromophenyl)-1H-pyrrol-3-yl]-N-(3,4-dichlorophenyl)methanimine (CAS 691870-07-2), a certified reference material (molecular formula C17H11BrCl2N2, MW 394.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C17H11BrCl2N2, (1E)-1-[1-(4-Bromophenyl)-1H-pyrrol-3-yl]-N-(3,4-dichlorophenyl)methanimine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 394.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), (1E)-1-[1-(4-Bromophenyl)-1H-pyrrol-3-yl]-N-(3,4-dichlorophenyl)methanimine 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.
