Chemical Structure

Terbinafine Impurity 45 CAS CATO-C4X-133845 chemical structure

Description

The occurrence of Terbinafine Impurity 45 is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Terbinafine Impurity 45 (CAS CATO-C4X-133845) is a certified pharmaceutical impurity reference standard with the molecular formula C7H12O and a molecular weight of 112.17 g/mol.

The molecular framework of Terbinafine Impurity 45 (C7H12O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

As a certified reference material (CRM), Terbinafine Impurity 45 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.
