4-Benzyl 2-ethyl 3-(2-ethoxy-2-oxoethyl)-5-methyl-1H-pyrrole-2,4-dicarboxylate (CAS 52887-35-1), molecular formula C20H23NO6 and molecular weight 373.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Benzyl 2-ethyl 3-(2-ethoxy-2-oxoethyl)-5-methyl-1H-pyrrole-2,4-dicarboxylate (C20H23NO6) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
