Febuxostat Impurity N3 CAS 104317-54-6

Description

Compared with other compounds in its class, the molecular weight of 153.20 g/mol gives Febuxostat Impurity N3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Febuxostat Impurity N3 (CAS 104317-54-6) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7NOS and a molecular weight of 153.20 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, Febuxostat Impurity N3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Febuxostat Impurity N3 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.
