Impurity reference standards

Uridine impurity standards

Zemixal lists 12 reference materials related to Uridine, covering the drug substance itself, its process impurities and the products it forms on storage. The list is made up mainly of process impurities, positional isomers and intermediates from common synthetic routes.

Batches are supplied with a certificate of analysis, and the supporting spectra can be sent ahead of a purchase order so your QA team can review them. Laboratories use them to validate related-substance methods, set specification limits under ICH Q3A and Q3B, and identify unknown peaks in stability samples.

Questions

Uridine impurities, answered

How many Uridine impurity standards does Zemixal list?

The catalogue currently lists 12 compounds for Uridine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.

What documents come with a Uridine 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 Uridine 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.
