Analysis Note

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

Application

Ibuprofen may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by spectrophotometry and chromatography techniques.
Ibuprofen may be used as a standard in the quantitative determination of ibuprofen in samples of human plasma using high performance liquid chromatography (HPLC). It may also be used as a reference standard in the determination of ibuprofen in dog plasma using liquid chromatography (LC).
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.

Biochem/physiol Actions

Cyclooxygenase (COX) inhibitor that has greater activity against COX-1 than against COX-2.
Cyclooxygenase (COX) inhibitor that has greater activity against COX-1 than against COX-2.

General description

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 is a substituted arylpropionic acid, used as a non-steroidal anti-inflammatory drug (NSAID).
