Chemical Structure
Description
Structurally, Lisinopril Impurity 25 (C25H40F3N3O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 535.60 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Lisinopril Impurity 25 (CAS 199002-00-1) is a certified pharmaceutical impurity reference standard with the molecular formula C25H40F3N3O6 and a molecular weight of 535.60 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.
