Dapoxetine Impurity 90 CAS CATO-C4X-143990

Description

Compared with other compounds in its class, the molecular weight of 134.18 g/mol gives Dapoxetine Impurity 90 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dapoxetine Impurity 90 (CAS CATO-C4X-143990) is a certified pharmaceutical impurity reference standard with the molecular formula C9H10O and a molecular weight of 134.18 g/mol.

Structurally, Dapoxetine Impurity 90 (C9H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 134.18 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Dapoxetine Impurity 90 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
