Lovastatin EP Impurity B CAS 75225-50-2

Description

Compared with other compounds in its class, the molecular weight of 444.54 g/mol gives Lovastatin EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lovastatin EP Impurity B (CAS 75225-50-2) is a certified pharmaceutical impurity reference standard with the molecular formula C24H37O6Na and a molecular weight of 444.54 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, Lovastatin EP Impurity B is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Lovastatin EP Impurity B 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.
