| 摘要 |
The present invention relates to a novel tri-iodinated compound, a manufacturing method for the novel tri-iodinated compound, and an X-ray contrast agent comprising the same and, more specifically, to a compound represented by Chemical Formula 1, a manufacturing method for the compound, and an X-ray contrast agent comprising the compound. In the present invention, a compound represented by the Chemical Formula 1 shows higher hydrophilicity and maintains lower osmolality than those of the X-ray contrast agent(CT contrast agent) which is currently used, and reduces pain which patients have when injected with the contrast agent. The compound can be used as a new contrast agent through a synthesis with other ligand. In the Chemical Formula 1, the R1 is NH2 or NHCOH. |
