Chemical Structure

Indocyanine green Impurity 58 CAS CATO-C4X-250358 chemical structure

Description

Indocyanine green Impurity 58 (C86H92N4O12S4Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Indocyanine green Impurity 58 (CAS CATO-C4X-250358) is a certified pharmaceutical impurity reference standard with the molecular formula C86H92N4O12S4Na and a molecular weight of 1524.93 g/mol.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Indocyanine green Impurity 58 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.
