Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 470.49 g/mol gives Etrasimod Impurity 51 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Etrasimod Impurity 51 (CAS CATO-C4X-321451), a pharmacopoeial impurity reference standard (molecular formula C26H28F6O, MW 470.49 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Etrasimod Impurity 51 (C26H28F6O) is characterized by a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Etrasimod Impurity 51 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.
