Description
CATO manufactures Rosuvastatin Impurity 37 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.
Rosuvastatin Impurity 37 (CAS 1197348-98-3) is a certified pharmaceutical impurity reference standard with the molecular formula C27H38FN3O6S and a molecular weight of 551.67 g/mol.
The molecular framework of Rosuvastatin Impurity 37 (C27H38FN3O6S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
