Analysis Note

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

Application

Dexamethasone may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using voltammentric techniques and reversed-phase high-performance liquid chromatography 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.

General description

Dexamethasone is a corticosteroid medication, with anti-inflammatory activity. It is widely used for inflammatory ocular conditions and for the treatment of skin-allergic reactions.
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.
