1-(2,5-Dichloro-4-nitrophenyl)-1H-pyrrole CAS 175135-54-3

Description

Compared with other compounds in its class, the molecular weight of 257.07 g/mol gives 1-(2,5-Dichloro-4-nitrophenyl)-1H-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2,5-Dichloro-4-nitrophenyl)-1H-pyrrole (CAS 175135-54-3), molecular formula C10H6Cl2N2O2 and molecular weight 257.07 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(2,5-Dichloro-4-nitrophenyl)-1H-pyrrole (C10H6Cl2N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 1-(2,5-Dichloro-4-nitrophenyl)-1H-pyrrole 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.
