Chemical Structure
Description
Based on its molecular formula C54H74N2O12C2F3O2, Atracurium Impurity 73 TFA salt contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1056.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Atracurium Impurity 73 TFA salt (CAS CATO-C4X-185073), a pharmacopoeial impurity reference standard (molecular formula C54H74N2O12C2F3O2, MW 1056.20 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.
