Chemical Structure

Selumetinib Impurity 5 CAS CATO-C4X-30535 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 209.18 g/mol gives Selumetinib Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Selumetinib Impurity 5 (CAS CATO-C4X-30535), a pharmacopoeial impurity reference standard (molecular formula C9H8FN3O2, MW 209.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H8FN3O2, Selumetinib Impurity 5 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 209.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Selumetinib Impurity 5 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.
