Selexipag Impurity 48 CAS CATO-C4X-196148

Description

Compared with other compounds in its class, the molecular weight of 245.36 g/mol gives Selexipag Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Selexipag Impurity 48 (CAS CATO-C4X-196148), a pharmacopoeial impurity reference standard (molecular formula C13H27NO3, MW 245.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Selexipag Impurity 48 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 245.36 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.

CATO manufactures Selexipag Impurity 48 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.
