Isosulfan Blue Impurity 5 CAS 2828260-22-4

Description

The occurrence of Isosulfan Blue Impurity 5 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Isosulfan Blue Impurity 5 (CAS 2828260-22-4), a pharmacopoeial impurity reference standard (molecular formula C17H19NO7S2, MW 413.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Isosulfan Blue Impurity 5 (C17H19NO7S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

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.

CATO manufactures Isosulfan Blue Impurity 5 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.
