Description

General description

Diethyl Phthalate is a phthalic acid ester, commonly synthesized by the condensation of the carboxy groups of phthalic acid with methanol.. It is used as a solvent for fragrance in cosmetic formulations and personal care products.
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

Diethyl Phthalate may be used as a pharmaceutical reference standard for the determination of the analyte in cosmetic products, pharmaceutical formulations and dietary supplements by chromatography.

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 primary standards, where they are available.
