Betaxolol EP Impurity D CAS 63659-16-5

Description

Compared with other compounds in its class, the molecular weight of 192.25 g/mol gives Betaxolol EP Impurity D distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Betaxolol EP Impurity D (CAS 63659-16-5, C12H16O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Betaxolol EP Impurity D (C12H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Betaxolol EP Impurity D 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.
