Description
CATO manufactures Indocyanine Green Impurity 53 Triethylamine Salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
Indocyanine Green Impurity 53 Triethylamine Salt (CAS CATO-C4X-250353) is a certified pharmaceutical impurity reference standard with the molecular formula C24H26NO4SC6H15N and a molecular weight of 525.73 g/mol.
Structurally, Indocyanine Green Impurity 53 Triethylamine Salt (C24H26NO4SC6H15N) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 525.73 g/mol, it falls into the moderately-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).
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.
