Chemical Structure
Description
Based on its molecular formula C23H28F3NO6, Fluoxetine Impurity 34(Mixture of Isomers) contains a flavonoid core, 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 471.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Fluoxetine Impurity 34(Mixture of Isomers) (CAS CATO-C4X-135234) is a certified pharmaceutical impurity reference standard with the molecular formula C23H28F3NO6 and a molecular weight of 471.47 g/mol.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
