Siponimod Impurity 28 TFA CAS CATO-C4X-247228

Description

The occurrence of Siponimod Impurity 28 TFA is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Siponimod Impurity 28 TFA (CAS CATO-C4X-247228) is a certified pharmaceutical impurity reference standard with the molecular formula C29H35F3N2O3C2HF3O2 and a molecular weight of 630.63 g/mol.

Siponimod Impurity 28 TFA (C29H35F3N2O3C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide 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 Siponimod Impurity 28 TFA 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.
