Chemical Structure

Etrasimod Impurity 63 CAS CATO-C4X-321463 chemical structure

Description

CATO manufactures Etrasimod Impurity 63 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.

Etrasimod Impurity 63 (CAS CATO-C4X-321463) is a certified pharmaceutical impurity reference standard with the molecular formula C7H16N4O2 and a molecular weight of 188.23 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Etrasimod Impurity 63 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
