2-Methyl-3-(n-methylsulfamoyl)benzoic acid CAS 1343675-33-1

Description

The occurrence of 2-Methyl-3-(n-methylsulfamoyl)benzoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Methyl-3-(n-methylsulfamoyl)benzoic acid (CAS 1343675-33-1) is a high-purity analytical reference standard with the molecular formula C9H11NO4S and a molecular weight of 229.25 g/mol.

2-Methyl-3-(n-methylsulfamoyl)benzoic acid (C9H11NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-Methyl-3-(n-methylsulfamoyl)benzoic 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.
