iohexol

Some examples of organic iodine molecules are iohexol, iodixanol and ioversol.

Despite this difference, iohexol is still considered a low-osmolality contrast agent; the osmolality of older agents, such as diatrizoate, may be more than twice as high.

A very similar product also manufactured by GE Healthcare is Omnipaque (Iohexol as the main drug substance).

The osmolality of iohexol ranges from 322 mOsm/kg-approximately 1.1 times that of blood plasma-to 844 mOsm/kg, almost three times that of blood.

Iohexol is a contrast agent, sold under the trade names Omnipaque and Exypaque; this compound is also sold as a density gradient medium under the names Accudenz, Histodenz and Nycodenz.
