Chemical Structure

Iloprost Impurity 2 CAS CATO-C4X-32022 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 378.50 g/mol gives Iloprost Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Iloprost Impurity 2 (CAS CATO-C4X-32022, C22H34O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Structurally, Iloprost Impurity 2 (C22H34O5) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 378.50 g/mol, it falls into the moderately-high-molecular-weight range. 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), Iloprost Impurity 2 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.
