4-Mercaptobiphenyl - Introduction
Biphenyl-4-thiol, the chemical formula is C12H10S, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: Biphenyl-4-thiol white solid or light yellow crystal.
-Solubility: It can be dissolved in organic solvents such as ethanol and acetone, but it does not dissolve in water.
-Melting point: Its melting point is approximately 68-70°C.
Use:
-Chemical reagents: Biphenyl-4-thiol are commonly used as intermediates in organic synthesis and can be used to synthesize other organic compounds.
-Surface modifier: Because its thiol group is metallophilic, it can be used to modify the metal surface and improve the adhesion between metal and organic matter.
-Optical materials: Because there are two benzene rings in the molecular structure of Biphenyl-4-thiol, it can be used to synthesize some optical materials, such as liquid crystal molecules.
Preparation Method:
Biphenyl-4-thiol can be prepared by the following steps:
1. Alkylation reaction of benzenethiol and biphenyl in an alkaline solvent to obtain 4-phenylphenylthiol compound (4-Phenyl-benzenethiol).
2. 4-Phenyl-benzenethiol is hydrogenated to obtain the target product Biphenyl-4-thiol.
Safety Information:
- Biphenyl-4-thiol is an organic compound that needs to be stored and handled in accordance with general laboratory safety measures, such as wearing suitable protective gloves and glasses and avoiding direct contact with skin and eyes.
-It is irritating and should be kept away from fire sources and avoid inhalation and ingestion.
-Maintain well-ventilated conditions during use or handling, and avoid contact with oxidants and strong acids to avoid possible dangerous reactions.
Please note that this is only a brief introduction to the Biphenyl-4-thiol, specific use and operation should refer to the relevant chemical literature and laboratory practice guidance.
