Chemical Structure
Description
As a certified reference material (CRM), 3-[(2-(Benzyloxycarbonyl)aminoacetyl)amino]-2,4,6-triiodoisophthaloyl Dichloride 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.
3-[(2-(Benzyloxycarbonyl)aminoacetyl)amino]-2,4,6-triiodoisophthaloyl Dichloride (CAS 1797114-29-4), molecular formula C18H11Cl2I3N2O5 and molecular weight 786.91 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(2-(Benzyloxycarbonyl)aminoacetyl)amino]-2,4,6-triiodoisophthaloyl Dichloride (C18H11Cl2I3N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
