Description
Desamino Chloro (S)-Fluoxetine (CAS 114446-51-4), molecular formula C16H14ClF3O and molecular weight 314.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Desamino Chloro (S)-Fluoxetine (C16H14ClF3O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 314.73 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
