Questions

Repaglinide impurities, answered

How many Repaglinide impurity standards does Zemixal list?

The catalogue currently lists 18 compounds for Repaglinide, including 6 pharmacopoeial impurities and 1 isotope-labelled standard. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.

What documents come with a Repaglinide 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 Repaglinide 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.

Are isotope-labelled Repaglinide standards available?

Yes. 1 stable-isotope labelled compound is listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
