Lusutrombopag Impurity 59 CAS CATO-C4X-208459

Description

Compared with other compounds in its class, the molecular weight of 591.55 g/mol gives Lusutrombopag Impurity 59 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lusutrombopag Impurity 59 (CAS CATO-C4X-208459) is a certified pharmaceutical impurity reference standard with the molecular formula C29H32Cl2N2O5S and a molecular weight of 591.55 g/mol.

Based on its molecular formula C29H32Cl2N2O5S, Lusutrombopag Impurity 59 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 591.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Lusutrombopag Impurity 59 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.
