Chemical Structure
Description
Guanosine Impurity 4 Disodium Salt (C14H18N7O10P2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl 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).
Guanosine Impurity 4 Disodium Salt (CAS 852155-68-1) is a certified pharmaceutical impurity reference standard with the molecular formula C14H18N7O10P2Na and a molecular weight of 529.27 g/mol.
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 Guanosine Impurity 4 Disodium 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.
