Chemical Structure

1-Methyl-5-sulfamoyl-1H-pyrrole-2-carboxylic acid CAS 306936-62-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.20 g/mol gives 1-Methyl-5-sulfamoyl-1H-pyrrole-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Methyl-5-sulfamoyl-1H-pyrrole-2-carboxylic acid (CAS 306936-62-9), a certified reference material (molecular formula C6H8N2O4S, MW 204.20 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methyl-5-sulfamoyl-1H-pyrrole-2-carboxylic acid (C6H8N2O4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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.
