Chemical Structure
Description
4-[(Ethylsulfonyl)(methyl)amino]benzoic acid (CAS 915909-03-4) is a high-purity analytical reference standard with the molecular formula C10H13NO4S and a molecular weight of 243.28 g/mol.
4-[(Ethylsulfonyl)(methyl)amino]benzoic acid (C10H13NO4S) 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), 4-[(Ethylsulfonyl)(methyl)amino]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.
