2-((1-(4-Bromophenyl)-1H-pyrrol-3-yl)methylene)malononitrile (CAS 439094-32-3), molecular formula C14H8BrN3 and molecular weight 298.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((1-(4-Bromophenyl)-1H-pyrrol-3-yl)methylene)malononitrile (C14H8BrN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine 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.

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), 2-((1-(4-Bromophenyl)-1H-pyrrol-3-yl)methylene)malononitrile 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.
