General description

Due to the unstable, hygroscopic nature of the free acid, the calcium salt is employed.
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.

Application

Calcium-d-pantothenate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by ion chromatography.
Precursor in the biosynthesis of coenzyme A.
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.

Analysis Note

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