Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 653.66 g/mol gives Relugolix Impurity 157 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Relugolix Impurity 157 (CAS CATO-C4X-2429157, C30H29F2N7O6S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Relugolix Impurity 157 (C30H29F2N7O6S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Relugolix Impurity 157 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.
