Description

Compared with other compounds in its class, the molecular weight of 273.33 g/mol gives 1-(2-Methoxyethyl)-2-methyl-5-(4-methylphenyl)-1H-pyrrole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(2-Methoxyethyl)-2-methyl-5-(4-methylphenyl)-1H-pyrrole-3-carboxylic acid (CAS 724744-82-5), a certified reference material (molecular formula C16H19NO3, MW 273.33 g/mol) for analytical method development and quality control.

1-(2-Methoxyethyl)-2-methyl-5-(4-methylphenyl)-1H-pyrrole-3-carboxylic acid (C16H19NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
