Questions
Fludarabine impurities, answered
What Fludarabine reference materials are available?
The catalogue currently lists 78 compounds for Fludarabine, including 8 pharmacopoeial impurities, 3 nitrosamines, 5 metabolites or hydroxylated analogues and 1 degradation product. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Fludarabine 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 Fludarabine 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.
Do you supply Fludarabine nitrosamine impurities?
Yes. 3 N-nitroso compounds are listed for Fludarabine. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
