Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 846.75 g/mol gives Netupitant Impurity 40 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Netupitant Impurity 40 (CAS CATO-C4X-122340) is a certified pharmaceutical impurity reference standard with the molecular formula C41H38F12N4O2 and a molecular weight of 846.75 g/mol.
Based on its molecular formula C41H38F12N4O2, Netupitant Impurity 40 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 846.75 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 Netupitant Impurity 40 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.
