Description

Compared with other compounds in its class, the molecular weight of 281.30 g/mol gives ethyl 5-(3-ethoxy-3-oxopropanoyl)-2,4-dimethyl-1H-pyrrole-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies ethyl 5-(3-ethoxy-3-oxopropanoyl)-2,4-dimethyl-1H-pyrrole-3-carboxylate (CAS 963-69-9), a certified reference material (molecular formula C14H19NO5, MW 281.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H19NO5, ethyl 5-(3-ethoxy-3-oxopropanoyl)-2,4-dimethyl-1H-pyrrole-3-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 281.30 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.
