Clofarabine impurity standards
Zemixal lists 11 reference materials related to Clofarabine, covering the drug substance itself, its process impurities and the products it forms on storage. Among them are 1 metabolite or hydroxylated analogue.
11reference materials
1metabolites
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. Typical uses are method development and validation, relative response factor work, forced degradation studies and the impurity sections of ANDA, DMF or CEP filings.

Questions
Clofarabine impurities, answered
How many Clofarabine impurity standards does Zemixal list?
The catalogue currently lists 11 compounds for Clofarabine, including 1 metabolite or hydroxylated analogue. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Clofarabine 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 Clofarabine 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.
