Chemical Structure

Loteprednol Impurity 13 CAS CATO-C4X-195713 chemical structure

Description

Loteprednol Impurity 13 (C47H60O14) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

Loteprednol Impurity 13 (CAS CATO-C4X-195713) is a certified pharmaceutical impurity reference standard with the molecular formula C47H60O14 and a molecular weight of 848.97 g/mol.

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), Loteprednol Impurity 13 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.
