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

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.
Docosanol can be used as a reference standard to develop and validate a GC/SIM-MS method to quantify docosanol in ex vivo human skin permeation studies. It can also be used in the analysis of olive oil quality and for determining its composition.

Analysis Note

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