Chemical Structure

Iloprost Impurity 9 CAS CATO-C4X-32029 chemical structure

Description

The occurrence of Iloprost Impurity 9 is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Iloprost Impurity 9 (CAS CATO-C4X-32029), a pharmacopoeial impurity reference standard (molecular formula C24H34O5, MW 402.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C24H34O5, Iloprost Impurity 9 contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 402.52 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), Iloprost Impurity 9 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.
