Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.19 g/mol gives Dapoxetine Impurity 86 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dapoxetine Impurity 86 (CAS 103548-16-9) is a certified pharmaceutical impurity reference standard with the molecular formula C9H12O2 and a molecular weight of 152.19 g/mol.
Dapoxetine Impurity 86 (C9H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
