Structurally, 2,2',2'',2'''-((((1,1-Dioxido-3H-benzo[c][1,2]oxathiole-3,3-diyl)bis(6-hydroxy-5-isopropyl-2-methyl-3,1-phenylene))bis(methylene))bis(azanetriyl))tetraacetic acid (C37H44N2O13S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 756.82 g/mol, it falls into the high-molecular-weight range. 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.
