Description
CATO manufactures Eltrombopag Impurity 97 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.
Eltrombopag Impurity 97 (CAS CATO-C4X-119897) is a certified pharmaceutical impurity reference standard with the molecular formula C27H27N5O4 and a molecular weight of 485.53 g/mol.
Based on its molecular formula C27H27N5O4, Eltrombopag Impurity 97 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 485.53 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.
