Description

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

Choline Bitartrate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by liquid chromatography (LC).

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.

Biochem/physiol Actions

Acyl group acceptor

Substrates

Choline acetyltransferase substrate
