4-(n-Isopropylsulfamoyl)-1-methyl-1h-pyrrole-2-carboxylic acid CAS 937611-13-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(n-Isopropylsulfamoyl)-1-methyl-1h-pyrrole-2-carboxylic acid.

4-(n-Isopropylsulfamoyl)-1-methyl-1h-pyrrole-2-carboxylic acid (CAS 937611-13-7), molecular formula C9H14N2O4S and molecular weight 246.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H14N2O4S, 4-(n-Isopropylsulfamoyl)-1-methyl-1h-pyrrole-2-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 246.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-(n-Isopropylsulfamoyl)-1-methyl-1h-pyrrole-2-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.
