2-(3-Chlorophenyl)-5-methyl-1-phenyl-1H-pyrrole CAS 918299-50-0

Description

The occurrence of 2-(3-Chlorophenyl)-5-methyl-1-phenyl-1H-pyrrole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3-Chlorophenyl)-5-methyl-1-phenyl-1H-pyrrole (CAS 918299-50-0), molecular formula C17H14ClN and molecular weight 267.75 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-(3-Chlorophenyl)-5-methyl-1-phenyl-1H-pyrrole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 267.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-(3-Chlorophenyl)-5-methyl-1-phenyl-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.
