Relugolix Impurity 43 CAS 593-56-6 chemical structure

Description

As a certified reference material (CRM), Relugolix Impurity 43 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.

Relugolix Impurity 43 (CAS 593-56-6) is a certified pharmaceutical impurity reference standard with the molecular formula CH5NOHCl and a molecular weight of 83.52 g/mol.

Based on its molecular formula CH5NOHCl, Relugolix Impurity 43 contains a hydroxyl group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 83.52 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.
