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.
Butylated hydroxytoluene (BHT) is a phenolic antioxidant used as a food additive. It is frequently added to dried cereals, cooking oils and animal foods. BHT is also known to enhance the stability of pharmaceuticals, fat-soluble vitamins and cosmetics .

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.

Analysis Note

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