Questions
Linagliptin impurities, answered
What Linagliptin reference materials are available?
The catalogue currently lists 84 compounds for Linagliptin, including 4 nitrosamines, 2 isotope-labelled standards, 1 metabolite or hydroxylated analogue and 6 degradation products. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Linagliptin 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 Linagliptin 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 Linagliptin nitrosamine impurities?
Yes. 4 N-nitroso compounds are listed for Linagliptin. 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 Linagliptin standards available?
Yes. 2 stable-isotope labelled compounds are listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
