Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
Application
Estrone may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques.
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.
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.
Estrone is a degradation product of the endogenous estrogen steroid, estradiol.
Estrone is a degradation product of the endogenous estrogen steroid, estradiol.
