Lovastatin Impurity 11 CAS CATO-C4X-168411

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lovastatin Impurity 11.

CATO supplies Lovastatin Impurity 11 (CAS CATO-C4X-168411), a pharmacopoeial impurity reference standard (molecular formula C20H30C2H4OC2H6, MW 344.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H30C2H4OC2H6, Lovastatin Impurity 11 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 344.58 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Lovastatin Impurity 11 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.
