Chemical Structure

4-Methyl-2-phenyl-1H-pyrrole CAS 20055-04-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 157.21 g/mol gives 4-Methyl-2-phenyl-1H-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Methyl-2-phenyl-1H-pyrrole (CAS 20055-04-3) is a high-purity analytical reference standard with the molecular formula C11H11N and a molecular weight of 157.21 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-2-phenyl-1H-pyrrole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 157.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-Methyl-2-phenyl-1H-pyrrole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
