Chemical Structure

Dimethyl 1-benzyl-3,4-dihydroxy-1H-pyrrole-2,5-dicarboxylate CAS 148528-45-4 chemical structure

Description

The molecular framework of Dimethyl 1-benzyl-3,4-dihydroxy-1H-pyrrole-2,5-dicarboxylate (C15H15NO6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Dimethyl 1-benzyl-3,4-dihydroxy-1H-pyrrole-2,5-dicarboxylate (CAS 148528-45-4) is a high-purity analytical reference standard with the molecular formula C15H15NO6 and a molecular weight of 305.28 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.
