Questions
Levetiracetam impurities, answered
How many Levetiracetam impurity standards does Zemixal list?
The catalogue currently lists 24 compounds for Levetiracetam, including 4 pharmacopoeial impurities, 1 isotope-labelled standard and 4 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 Levetiracetam 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 Levetiracetam 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.
Are isotope-labelled Levetiracetam standards available?
Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
