Chemical Structure
Description
The occurrence of Lenvatinib Impurity 70 is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Lenvatinib Impurity 70 (CAS 56962-03-9) is a high-purity analytical reference standard with the molecular formula C6H5Cl2NO and a molecular weight of 178.02 g/mol.
Structurally, Lenvatinib Impurity 70 (C6H5Cl2NO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 178.02 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
