Store in a sealed and protected place from light

Synthesis method

1. Made from 17?-estradiol under the action of 17?-hydroxysteroid dehydrogenase.

2.

Purpose

1. It is mainly used to treat uterine hypoplasia, menstrual disorders, menopausal disorders, etc. It is rarely used due to its difficult source.
