3-Hydroxyphenylacetylene

3-ethynylphenol is an organic compound that is a colorless liquid at room temperature. It is reactive, with a pKa of 9.3, and has been shown to be protonated in water at pH 7.3. 3-ethynylphenol has been shown to react with phenyl groups and has a high transport property due to its ability to permeate through the lipid bilayer of biological membranes. The nucleophilicity of 3-ethynylphenol facilitates reactions with electron-rich aromatic molecules such as nitrobenzene and benzaldehyde, which act as model substrates for bacterial enzymes. 3-ethynylphenol is synthesized by the reaction of ethyne with formaldehyde in the presence of a reducing agent under acidic conditions. Structural analysis shows that it consists of three phenyl groups connected via carbon atoms on each side (hence the name). This compound can be used for the synthesis of other compounds or as a
