Chemical Structure

Dapoxetine Impurity 5 CAS 1329834-62-9 chemical structure

Description

As a process- or degradation-related impurity, Dapoxetine Impurity 5 (CAS 1329834-62-9, C19H19NO) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Dapoxetine Impurity 5 (C19H19NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 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.

As a certified reference material (CRM), Dapoxetine Impurity 5 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
