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. They are bought for system suitability, peak identification, quantitation against limits and the impurity justification sections of regulatory submissions. The nitrosamine entries support ICH M7 risk assessments and confirmatory testing at trace levels.

Questions
Etomidate impurities, answered
How many Etomidate impurity standards does Zemixal list?
The catalogue currently lists 8 compounds for Etomidate, including 2 pharmacopoeial impurities and 1 nitrosamine. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Etomidate 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 Etomidate 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 Etomidate nitrosamine impurities?
Yes. 1 N-nitroso compound is listed for Etomidate. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
