Impurity reference standards
Ioversol impurity standards
This page brings together 4 Ioversol related compounds that analytical teams use to identify, quantify and control impurities in the active ingredient and the finished dosage form. The range includes 3 metabolites or hydroxylated analogues.
4reference materials
3metabolites
Every standard comes with a certificate of analysis. Structure confirmation data, typically NMR, MS and chromatographic purity, is available on request. They are bought for system suitability, peak identification, quantitation against limits and the impurity justification sections of regulatory submissions.

Questions
Ioversol impurities, answered
What Ioversol reference materials are available?
The catalogue currently lists 4 compounds for Ioversol, including 3 metabolites or hydroxylated analogues. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Ioversol impurity standard?
A certificate of analysis travels with every lot. On request we share the characterisation set, usually 1H-NMR, mass spectrum, HPLC purity and IR, and for some materials TGA or water content. Ask for the data before ordering if your QA team needs to review it.
Can Zemixal make a Ioversol impurity that is not listed?
Often yes. Send the structure, name or CAS number with the quantity you need and our sourcing team checks custom synthesis options, usually from 10 mg up to gram scale, with a quoted lead time.
