Iohexol Introduction

Iohexol is the raw material of contrast agent, which is usually injected into the vein before CT angiography and used for angiography, urinary system, spinal cord and femoral joint, and lymphatic system angiography. It has the advantages of low contrast density, low toxicity, and good tolerance, and is one of the best contrast agents at present.

Iohexol is an iodinated medium for nonionic gradation. It shows a maximum absorption spectrum at 244 nm, hence it is not suitable for spectrophotometric analyses in the ultraviolet range.
