CATO supplies Ammonium 2,2'-((2-(2-(2-(bis(carboxylatomethyl)amino)-5-(2,7-dichloro-6-oxido-3-oxo-3H-xanthen-9-yl)phenoxy)ethoxy)-4-methylphenyl)azanediyl)diacetate (CAS 339221-91-9), a certified reference material (molecular formula C36H25Cl2N2O13H4N, MW 782.54 g/mol) for analytical method development and quality control.
Ammonium 2,2'-((2-(2-(2-(bis(carboxylatomethyl)amino)-5-(2,7-dichloro-6-oxido-3-oxo-3H-xanthen-9-yl)phenoxy)ethoxy)-4-methylphenyl)azanediyl)diacetate (C36H25Cl2N2O13H4N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Ammonium 2,2'-((2-(2-(2-(bis(carboxylatomethyl)amino)-5-(2,7-dichloro-6-oxido-3-oxo-3H-xanthen-9-yl)phenoxy)ethoxy)-4-methylphenyl)azanediyl)diacetate 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.
