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.
Naproxen belongs to the class of arylacetic acids and is used as a non-steroidal anti-inflammatory drug (NSAID). It is useful for the management of pain, inflammation and stiffness. It is also used in the treatment of rheumatoid arthritis and other painful musculoskeletal disorders.
Naproxen belongs to the class of arylacetic acids and is used as a non-steroidal anti-inflammatory drug (NSAID). It is useful for the management of pain, inflammation and stiffness. It is also used in the treatment of rheumatoid arthritis and other painful musculoskeletal disorders.
Application
Naproxen may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by high performance liquid chromatography (HPLC) technique.
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
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor.
Analysis Note
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
Other Notes
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.
