Általános leírás

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.
Estradiol is a steroid hormone present naturally in the human body. The availability of this hormone is quintessential in older women as it is a determinant of menopausal syndromes. It is utilized for the prevention of cardiovascular diseases.

Alkalmazás

Estradiol 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.

Biokémiai/fiziológiai hatások

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.

Analízis megjegyzés

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

Egyéb megjegyzések

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
