Chemical Structure
Description
Based on its molecular formula C36H48D5N7O6HCl, Difelikefalin Impurity 78 contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 721.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Difelikefalin Impurity 78 (CAS CATO-C4X-304178) is a certified pharmaceutical impurity reference standard with the molecular formula C36H48D5N7O6HCl and a molecular weight of 721.35 g/mol.
