The occurrence of N-Ethyl-N-(3-sulfobenzyl)sulfanilic Acid Disodium Salt is closely related to a flavonoid core, 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.
N-Ethyl-N-(3-sulfobenzyl)sulfanilic Acid Disodium Salt (CAS 5363-53-1), molecular formula C15H15NO6S2Na and molecular weight 392.40 g/mol, is a CATO reference standard with documented purity and traceability.
N-Ethyl-N-(3-sulfobenzyl)sulfanilic Acid Disodium Salt (C15H15NO6S2Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
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.
CATO manufactures N-Ethyl-N-(3-sulfobenzyl)sulfanilic Acid Disodium Salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
