Questions
Ibuprofen impurities, answered
How many Ibuprofen impurity standards does Zemixal list?
The catalogue currently lists 73 compounds for Ibuprofen, including 16 pharmacopoeial impurities, 2 isotope-labelled standards and 4 metabolites or hydroxylated analogues. Each product page shows the CAS number where one is assigned, the structure, formula and molecular weight.
What documents come with a Ibuprofen 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 Ibuprofen 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 Ibuprofen standards available?
Yes. 2 stable-isotope labelled compounds are listed, suitable as internal standards for LC-MS bioanalysis and trace impurity quantitation.
