iohexol and its Impurities
Iohexol is used in myelography, arthrography, nephroangiography, arteriography, and other radiographic procedures. It is an effective non-ionic, water-soluble contrast agent. Its low systemic toxicity is the combined result of low chemotoxicity and low osmolality. Reference standards of Iohexol API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
