Impurity reference standards
Eprosartan impurity standards
For Eprosartan, the Zemixal catalogue holds 8 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Most entries are process-related impurities, synthesis intermediates and isomers.
8reference materials
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
Eprosartan impurities, answered
What Eprosartan reference materials are available?
The catalogue currently lists 8 compounds for Eprosartan. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Eprosartan 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 Eprosartan 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.
