Chemical Structure

Lovastatin Impurity 32 CAS CATO-C4X-168432 chemical structure

Description

CATO supplies Lovastatin Impurity 32 (CAS CATO-C4X-168432), a pharmacopoeial impurity reference standard (molecular formula C19H34O2C2H6, MW 324.55 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lovastatin Impurity 32 (C19H34O2C2H6) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Impurity 32 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.
