3-Amino-5-[[[2,3-bis(acetyloxy)propyl]amino]carbonyl]-2,4,6-triiodo-benzoic acid CAS 122731-59-3

Description

3-Amino-5-[[[2,3-bis(acetyloxy)propyl]amino]carbonyl]-2,4,6-triiodo-benzoic acid (C15H15I3N2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).

3-Amino-5-[[[2,3-bis(acetyloxy)propyl]amino]carbonyl]-2,4,6-triiodo-benzoic acid (CAS 122731-59-3), molecular formula C15H15I3N2O7 and molecular weight 716.00 g/mol, is a CATO reference standard with documented purity and traceability.

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.
