X-ray contrast agent purification |
| abstract |
A method for the purification of a crude non-ionic iodinated dimeric X-ray contrast agent product, comprising the step of: i) passing a solution of the crude product through a membrane (M1) such that impurities of monomeric compounds and salts cross the membrane (permeate, P1) and the nonionic iodinated dimeric X-ray contrast agent passes over the membrane (retained, R1), providing a purified dimeric X-ray contrast agent having a purity of at least 98%; where the impurities of monomeric compounds are compounds that have a molecular weight between 435 and 900 Da, and where M1 has a cut size between 950 and 1,200 Da. |
