Analysis Note

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

Application

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.
Valsartan may be used as a pharmaceutical reference standard for the determination of the analyte in tablet formulations, bulk and pharmaceutical dosage forms using reversed-phase high-performance liquid chromatography technique.

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. Valsartan Related Compound A is an impurity of valsartan, an orally active specific angiotensin II receptor blocker or angiotensin-II antagonist, which is widely used in treating hypertension by lowering the blood pressure.

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.
