Description
As a certified reference material (CRM), Lenacapavir Impurity 87 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.
Lenacapavir Impurity 87 (CAS CATO-C4X-32487) is a certified pharmaceutical impurity reference standard with the molecular formula C39H31ClF10N7O5S2 and a molecular weight of 967.27 g/mol.
Structurally, Lenacapavir Impurity 87 (C39H31ClF10N7O5S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 22.5, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 967.27 g/mol, it falls into the high-molecular-weight range. 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.
