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
Vincristine impurities, answered
How many Vincristine impurity standards does Zemixal list?
The catalogue currently lists 6 compounds for Vincristine, including 3 pharmacopoeial impurities and 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 Vincristine 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 Vincristine 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.
