Description

Analysis Note

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

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.

Triethyl citrate can be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by chromatography.[1][2]

General description

Triethyl citrate is an ester of citric acid and is commonly used as a plasticizer in pharmaceutical coatings including tablets, capsules, beads and granules for masking taste. It is also used as a flavoring agent in food.[3][4]

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.
