Common Name | 4-Methoxy-17beta-estradiol |
---|
Description | 4-Methoxy-17beta-estradiol, also known as 4-methoxyestradiol or 4-ME2, is a member of the class of compounds known as estrogens and derivatives. These compounds are steroids with a structure containing a 3-hydroxylated estrane. 4-Methoxy-17beta-estradiol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 4-Methoxy-17beta-estradiol can be synthesized from 17beta-estradiol. 4-Methoxy-17beta-estradiol can also be synthesized into 4-methoxy-17beta-estradiol 3-O-(beta-D-glucuronide). |
