Impurity reference standards
Citicoline impurity standards
For Citicoline, the Zemixal catalogue holds 4 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Most entries are process-related impurities, synthesis intermediates and isomers.
4reference materials
Each lot ships with a certificate of analysis, and characterisation data such as 1H-NMR, mass spectrum and HPLC purity can be shared before you order. Laboratories use them to validate related-substance methods, set specification limits under ICH Q3A and Q3B, and identify unknown peaks in stability samples.

Questions
Citicoline impurities, answered
What Citicoline reference materials are available?
The catalogue currently lists 4 compounds for Citicoline. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Citicoline 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 Citicoline 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.
