Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lumateperone Impurity 21.
Lumateperone Impurity 21 (CAS CATO-C4X-220121) is a certified pharmaceutical impurity reference standard with the molecular formula C10H9FO and a molecular weight of 164.18 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Lumateperone Impurity 21 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.18 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.
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), Lumateperone Impurity 21 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.
