General description

Ibuprofen Impurity F is an impurity of the drug, ibuprofen. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that is effective against pain, inflammation and fever. It is deemed as a safe drug on account of its reversible inhibitory effects on cyclooxygenase (COX) enzyme along with its unique pharmacokinetics.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.


Ibuprofen may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by analytical techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes
