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 It is the structural analog of two drugs, the never-marketed antiestrogen ethamoxytriphetol (MER-25)[1]: 7  and the withdrawn lipid-lowering agent triparanol,[2] as both contain the 1,1,2-triphenylethanol moiety within their structure.

There are three isomeric compounds with a "triphenylethanol" structure:

• 1,1,2-triphenylethanol;
• 1,2,2-triphenylethanol, with a condensed structural formula of (C
  ₆H
  ₅)
  ₂CHCH(C
  ₆H
  ₅)OH, which exists as a pair of enantiomers; and,
• 2,2,2-triphenylethanol, with a condensed structural formula of (C
  ₆H
  ₅)
  ₃CCH
  ₂OH.
