4-Mercaptophenol Chemical Properties,Usage,Production

Chemical Properties

Clear colorless to light yellow solid or liquid

Uses

4-Mercaptophenol was used as a resin monomer in the study of the different gold nanocrystal core-resin shell structures.

Uses

4-Mercaptophenol (MPH) has been used to study the adsorption of MPH on silver coated polystyrene nanospheres by time-dependent surface-enhanced Raman scattering (SERS) spectroscopy.
4-Mercaptophenol may be used in the preparation of silylated monomer, which was employed for the synthesis of hyperbranched poly(ester-imide). 4-Mercaptophenol (H-4MP) reacts with metal tert-butoxides ([M(OBu^t)₄]) to yield the following Group 4 phenoxy-thiols:

[(HOBu^t)(4MP)₃M(μ-4MP)]₂, where M = Ti, Zr, Hf
[(py)₂M(4MP)], where M = Ti, Zr; py = pyridine
[(py)(4MP)₃Hf(μ-4MP)]₂

4-Mercaptophenol may be used in the synthesis of the following:

poly(ethersulfide)s via silylation followed by polycondensation with 2,6-dichloropyridine or 3,6-dichloropyridazine
2,6-di-tertiarybutyl-4-mercaptophenol via Friedel-Craft′s alkylation with tert-butyl chloride in presence of a lewis acid

General Description

The density function theory calculations were performed to infer the IR and Raman spectra for 4-mercaptophenol molecule.
