Chemical Structure
Description
The molecular framework of ethyl 5-[(acetyloxy)methyl]-4-ethyl-3-methyl-1H-pyrrole-2-carboxylate (C13H19NO4) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
ethyl 5-[(acetyloxy)methyl]-4-ethyl-3-methyl-1H-pyrrole-2-carboxylate (CAS 100619-73-6) is a high-purity analytical reference standard with the molecular formula C13H19NO4 and a molecular weight of 253.29 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.
