Every standard comes with a certificate of analysis. Structure confirmation data, typically NMR, MS and chromatographic purity, is available on request. Typical uses are method development and validation, relative response factor work, forced degradation studies and the impurity sections of ANDA, DMF or CEP filings. The nitrosamine entries support ICH M7 risk assessments and confirmatory testing at trace levels.

Questions
Naratriptan impurities, answered
How many Naratriptan impurity standards does Zemixal list?
The catalogue currently lists 24 compounds for Naratriptan, including 2 pharmacopoeial impurities, 1 nitrosamine, 1 isotope-labelled standard 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 Naratriptan 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 Naratriptan 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 Naratriptan nitrosamine impurities?
Yes. 1 N-nitroso compound is listed for Naratriptan. They are used for confirmatory testing and method validation in line with ICH M7 and the nitrosamine guidance from the major regulators.
Are isotope-labelled Naratriptan standards available?
Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
