Chemical Structure

Siponimod Impurity 36 CAS CATO-C4X-247236 chemical structure

Description

CATO supplies Siponimod Impurity 36 (CAS CATO-C4X-247236), a pharmacopoeial impurity reference standard (molecular formula C31H37F3N2O3, MW 542.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Siponimod Impurity 36 (C31H37F3N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 542.63 g/mol, it falls into the moderately-high-molecular-weight range. 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 Siponimod Impurity 36 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.
