Nature:
-Appearance: 4-Methoxybenzyl mercaptan is a colorless to light yellow liquid.
-Odor: Has a strong smell of sulfur.
-Melting point:-40°C
-Boiling point: 248°C
-Density: Approximately 1.1 g/mL
-Solubility: Soluble in organic solvents such as ether, ethanol and dichloromethane.
Use:
- 4-Methoxybenzyl mercaptan is an important organic intermediate and has a wide range of applications in organic synthesis. It can be used as a starting material for the preparation of plant growth regulators, pharmaceutical intermediates, fine chemicals and other compounds.
Preparation Method:
- 4-Methoxybenzyl mercaptan are usually synthesized by reacting benzyl chloride with methoxysulfane (CH3SCH3) under basic conditions. The specific synthesis step may be first reacting benzyl chloride with sodium hydroxide (NaOH) in an alkaline alcohol solution to obtain the corresponding benzyl alcohol, and then reacting with methyl mercaptan in alkaline ethanol or dichloromethane to obtain 4-Methoxybenzene mercaptan.
Safety Information:
