2-((4-Ethyl-3,5-dimethyl-2H-pyrrol-2-ylidene)methyl)-3,4-dimethyl-1H-pyrrole CAS 732181-75-8

Description

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.

2-((4-Ethyl-3,5-dimethyl-2H-pyrrol-2-ylidene)methyl)-3,4-dimethyl-1H-pyrrole (CAS 732181-75-8), molecular formula C15H20N2 and molecular weight 228.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-((4-Ethyl-3,5-dimethyl-2H-pyrrol-2-ylidene)methyl)-3,4-dimethyl-1H-pyrrole (C15H20N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
