Chemical Structure
Description
The occurrence of Glutathione Impurity 11 is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Glutathione Impurity 11 (CAS CATO-C4X-118511), a pharmacopoeial impurity reference standard (molecular formula C10H14N3O8SNa, MW 359.28 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C10H14N3O8SNa, Glutathione Impurity 11 contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 359.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Glutathione Impurity 11 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.
