3-Hydroxythiophenol Usage And Synthesis

Chemical Properties

Colorless liquid

Uses

3-mercaptophenol may be used in the synthesis of the following:

• 4-(3-hydroxyphenylthio)naphthalene-1,2-dione, which shows fluorosence emission
• [C₆H₄-1-(SPPh₂)-3-(OPPh₂)], a non-symmetric ligand which can combine with PdCl₂ to form a pincer complex

General Description

3-mercaptophenol coated cantilevers can be used as formaldehyde sensors since it is highly selective towards formaldehyde and can show highest downward deflection on coming in contact with it.
