Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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.

Biochem./physiol. Wirkung

Das von prämenopausalen Eierstöcken hauptsächlich sezernierte Östrogen. Östrogene steuern die Entwicklung des weiblichen Phänotyps in der Embryogenese und während der Pubertät durch Regulierung der Gentranskription und folglich der Proteinsynthese. Sie induzieren auch die Produktion der Gonadotropine, welche wiederum die Ovulation auslösen. Die Exposition an Estradiol ist mit einer erhöhten Brustkrebsinzidenz und -proliferation assoziiert.

Hinweis zur Analyse

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