Description

General description

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.

Application

α-Tocopheryl acetate may be used as an internal standard in the determination of α-tocopherol in human serum or plasma samples using high performance chromatography (HPLC). It may also be used pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectrophotometric 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.

Analysis Note

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