Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 309.33 g/mol gives Fluoxetine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fluoxetine (CAS 54910-89-3) is a high-purity analytical reference standard with the molecular formula C17H18F3NO and a molecular weight of 309.33 g/mol.
Fluoxetine (C17H18F3NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
