Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fondaparinux sodium impurity 2.
Fondaparinux sodium impurity 2 (CAS CATO-C4X-20522) is a certified pharmaceutical impurity reference standard with the molecular formula C31H44N3O46S7Na and a molecular weight of 1442.08 g/mol.
Fondaparinux sodium impurity 2 (C31H44N3O46S7Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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 Fondaparinux sodium impurity 2 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.
