Chemical Structure

Elagolix Impurity 19 CAS 927-58-2 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, Elagolix Impurity 19 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 185.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies Elagolix Impurity 19 (CAS 927-58-2), a pharmacopoeial impurity reference standard (molecular formula C4H6BrClO, MW 185.45 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Elagolix Impurity 19 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.
