17-Epiestriol

CAS 1228-72-4: 17-Epiestriol

Description:17-Epiestriol, with the CAS number 1228-72-4, is a naturally occurring steroid hormone that is a derivative of estriol, which is one of the three main estrogens produced by the human body. It is characterized by its structure, which includes a phenolic A-ring and a hydroxyl group at the C-17 position, contributing to its estrogenic activity. This compound is primarily involved in the regulation of various physiological processes, including reproductive functions and menstrual cycles. 17-Epiestriol is known for its relatively weak estrogenic potency compared to other estrogens like estradiol. It is often studied in the context of hormone replacement therapy and its potential effects on bone density and cardiovascular health. Additionally, it has been investigated for its role in pregnancy, as it is produced in significant amounts by the placenta. Its solubility in organic solvents and its stability under physiological conditions make it a subject of interest in both clinical and research settings.
