General description

This product is provided as delivered and specified by the issuing Pharmacopoeia. All information provided in support of this product, including SDS and any product information leaflets have been developed and issued under the Authority of the issuing Pharmacopoeia.For further information and support please go to the website of the issuing Pharmacopoeia.

Application

Estradiol USP reference standard for use in specified quality tests and assays.

Also used to prepare standard and system suitability solution for assay, performance test, and impurity analysis according to the given below monographs of United States Pharmacopeia (USP):
  • Estradiol Cypionate
  • Estradiol and Norethindrone Acetate Tablets

Biochem/physiol Actions

The major estrogen secreted by the premenopausal ovary. Estrogens direct the development of the female phenotype in embryogenesis and during puberty by regulating gene transcription and, thus, protein synthesis. It also induces the production of gonadotropins which, in turn, induce ovulation. Exposure to estradiol increases breast cancer incidence and proliferation.

Analysis Note
