Description
As a certified reference material (CRM), Atosiban Impurity 23 TFA Salt 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.
CATO supplies Atosiban Impurity 23 TFA Salt (CAS CATO-C4X-229323), a pharmacopoeial impurity reference standard (molecular formula C86H134N22O24S4C2HF3O2, MW 2102.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C86H134N22O24S4C2HF3O2, Atosiban Impurity 23 TFA Salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 2102.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
