3-(Trifluoromethoxy)phenol

Updated: 2026-07-29

Overview

3-(Trifluoromethoxy)phenol is an organic compound with the molecular formula C7H5F3O2. It is a derivative of phenol where a trifluoromethoxy group is attached to the meta position of the benzene ring. This compound is primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its unique chemical properties. Its structure combines the aromaticity of phenol with the electron-withdrawing effects of the trifluoromethoxy group, making it a versatile building block in organic chemistry. The compound is typically supplied as a colorless to pale yellow liquid and is handled with care due to its reactivity.
