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It is the structural analog of two drugs, the never-marketed antiestrogen ethamoxytriphetol (MER-25)^{[1]: 7 } and the withdrawn lipid-lowering agent triparanol,^[2] as both contain the 1,1,2-triphenylethanol moiety within their structure.
