Methyl 1-(4-bromophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1H-pyrrole-3-carboxylate CAS 881041-39-0

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.

CATO supplies Methyl 1-(4-bromophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1H-pyrrole-3-carboxylate (CAS 881041-39-0), a certified reference material (molecular formula C21H20BrNO2, MW 398.29 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Methyl 1-(4-bromophenyl)-5-(3,4-dimethylphenyl)-2-methyl-1H-pyrrole-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
