Impurity reference standards
Valine impurity standards
For Valine, the Zemixal catalogue holds 10 impurity and reference standards that support release testing, stability programmes and regulatory dossiers. Most entries are process-related impurities, synthesis intermediates and isomers.
10reference materials
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
Valine impurities, answered
What Valine reference materials are available?
The catalogue currently lists 10 compounds for Valine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Valine 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 Valine 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.
