Chemical Structure

3,4-Dimethyl 1h-pyrrole-3,4-dicarboxylate CAS 2818-06-6 chemical structure

Description

Based on its molecular formula C8H9NO4, 3,4-Dimethyl 1h-pyrrole-3,4-dicarboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 183.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

3,4-Dimethyl 1h-pyrrole-3,4-dicarboxylate (CAS 2818-06-6) is a high-purity analytical reference standard with the molecular formula C8H9NO4 and a molecular weight of 183.16 g/mol.

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.
