Lemborexant Impurity 43 CAS CATO-C4X-304243

Description

Compared with other compounds in its class, the molecular weight of 346.31 g/mol gives Lemborexant Impurity 43 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Lemborexant Impurity 43 (CAS CATO-C4X-304243, C17H15FN2O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Lemborexant Impurity 43 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Lemborexant Impurity 43 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.
