Chemical Structure

1-(2-Methoxyethyl)-5-(4-methoxyphenyl)-2-methyl-1H-pyrrole-3-carboxylic acid CAS 879329-80-3 chemical structure

Description

The molecular framework of 1-(2-Methoxyethyl)-5-(4-methoxyphenyl)-2-methyl-1H-pyrrole-3-carboxylic acid (C16H19NO4) 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 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).

1-(2-Methoxyethyl)-5-(4-methoxyphenyl)-2-methyl-1H-pyrrole-3-carboxylic acid (CAS 879329-80-3), molecular formula C16H19NO4 and molecular weight 289.33 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 1-(2-Methoxyethyl)-5-(4-methoxyphenyl)-2-methyl-1H-pyrrole-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
