Chemical Structure
Description
Based on its molecular formula C22H29F3N4O, ZHC-116 Impurity 8 contains a steroid core, 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 422.49 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.
ZHC-116 Impurity 8 (CAS CATO-C4X-23888) is a certified pharmaceutical impurity reference standard with the molecular formula C22H29F3N4O and a molecular weight of 422.49 g/mol.
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.
