Methyl 3-[(Z)-(dimethylamino)methylidene]-1-[2-(1H-indol-3-yl)ethyl]-5-methyl-2-oxo-1,2-dihydro-3H-pyrrole-4-carboxylate CAS 477871-89-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-[(Z)-(dimethylamino)methylidene]-1-[2-(1H-indol-3-yl)ethyl]-5-methyl-2-oxo-1,2-dihydro-3H-pyrrole-4-carboxylate.

CATO supplies Methyl 3-[(Z)-(dimethylamino)methylidene]-1-[2-(1H-indol-3-yl)ethyl]-5-methyl-2-oxo-1,2-dihydro-3H-pyrrole-4-carboxylate (CAS 477871-89-9), a certified reference material (molecular formula C20H23N3O3, MW 353.41 g/mol) for analytical method development and quality control.

Based on its molecular formula C20H23N3O3, Methyl 3-[(Z)-(dimethylamino)methylidene]-1-[2-(1H-indol-3-yl)ethyl]-5-methyl-2-oxo-1,2-dihydro-3H-pyrrole-4-carboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 353.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
