Lercanidipine Impurity 52 CAS CATO-C4X-136452

Description

Compared with other compounds in its class, the molecular weight of 262.75 g/mol gives Lercanidipine Impurity 52 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lercanidipine Impurity 52 (CAS CATO-C4X-136452), a pharmacopoeial impurity reference standard (molecular formula C11H15ClO3S, MW 262.75 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lercanidipine Impurity 52 (C11H15ClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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.

As a certified reference material (CRM), Lercanidipine Impurity 52 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.
