Description
Duloxetine EP Impurity F Oxalate (CAS 2379325-42-3) is a certified pharmaceutical impurity reference standard with the molecular formula C18H19NOSC2H2O4 and a molecular weight of 387.45 g/mol.
Based on its molecular formula C18H19NOSC2H2O4, Duloxetine EP Impurity F Oxalate contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 387.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Duloxetine EP Impurity F Oxalate 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.
