Description

General description

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

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.

It is an impurity of the nonsteroidal anti-inflammatory drug (NSAID)― ibuprofen, used for the treatment of mild and moderate pain such as rheumatoid arthritis, osteoarthritis, and dysmenorrhea.

Application

This pharmaceutical secondary standard can also be used as follows:

• Development of a reverse-phase ultraperformance liquid chromatographic (RP-UPLC) method for the estimation of ibuprofen and diphenhydramine citrate along with their related impurities in their combined dosage form
• Simultaneous determination of ibuprofen and its 17 related impurities by an ICH validated reversed-phase high-performance liquid chromatography (RP-HPLC) method in tablets

Analysis Note

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