Triphenylethanol

Triphenylethanol, or 1,1,2-triphenylethanol, is an organic compound with a condensed structural formula of, 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 It is the structural analog of two drugs, the never-marketed antiestrogen ethamoxytriphetol and the withdrawn lipid-lowering agent triparanol, as both contain the 1,1,2-triphenylethanol moiety within their structure.
There are three isomeric compounds with a "triphenylethanol" structure:

1,1,2-triphenylethanol;
1,2,2-triphenylethanol, with a condensed structural formula of, which exists as a pair of enantiomers; and,
2,2,2-triphenylethanol, with a condensed structural formula of.
