Of the molecular mass, 45.6% is contributed by the three iodine atoms.<unk>  is nonionic but water-soluble, having a number of OH groups in its side chains designed to mask the central hydrophobic benzene ring. The solution has a low osmolarity of 695 (Xenetix 300) or 915 mOsm/kg H2O (Xenetix 350), which means it causes fewer allergic and allergy-like reactions, as well as less extravasation (leakage of blood vessels), than contrast agents with higher osmolarities.
