Chemical Structure

Rosuvastatin Impurity 61 CAS 124752-23-4 chemical structure

Description

Based on its molecular formula C13H22O5, Rosuvastatin Impurity 61 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Rosuvastatin Impurity 61 (CAS 124752-23-4) is a certified pharmaceutical impurity reference standard with the molecular formula C13H22O5 and a molecular weight of 258.31 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), Rosuvastatin Impurity 61 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.
