Fesoterodine Impurity N95 CAS 1333234-73-3

Description

Compared with other compounds in its class, the molecular weight of 527.66 g/mol gives Fesoterodine Impurity N95 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fesoterodine Impurity N95 (CAS 1333234-73-3), a pharmacopoeial impurity reference standard (molecular formula C26H37NO3C4H4O4, MW 527.66 g/mol) used for the identification and quantification of trace impurities in APIs.

Fesoterodine Impurity N95 (C26H37NO3C4H4O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Fesoterodine Impurity N95 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.
