Triphenylethanol

Triphenylethanol, or 1,1,2-triphenylethanol, is an organic compound with a condensed structural formula of (C
6H
5)
2C(OH)CH
2C
6H
5, and is related to triphenylethylene, from which it can be prepared by hydration. It is the structural analog of two drugs, the never-marketed antiestrogen ethamoxytriphetol (MER-25): 7  and the withdrawn lipid-lowering agent triparanol, as both contain the 1,1,2-triphenylethanol moiety within their structure.
