2-MERCAPTOPHENOL FOR SYNTHESIS - Introduction
2-Hydroxythiophenol, also known as 2-hydroxythiophenol, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
The chemical formula of 2-hydroxythiophenol is C6H6OS, which is a colorless to slightly yellow solid. It has a melting point of 37-40 degrees Celsius and a boiling point of 293 degrees Celsius. 2-Hydroxythiophenol is soluble in ether and alcohol solvents and slightly soluble in water. It has the properties of phenols and thiols and can be oxidized by oxidants.
Use:
2-hydroxythiophenol is commonly used as raw materials and intermediates in organic synthesis. It is widely used in dye, medicine and rubber industry. In some catalytic reactions, 2-hydroxythiophenol can also be used as a catalyst.
Preparation Method:
A common method for preparing 2-hydroxythiophenol is obtained by reacting p-methylthiophenol with alkaline hydrogen peroxide. Specifically, thiophenol reacts with hydrogen peroxide under alkaline conditions to produce 2-hydroxythiophenol.
Safety Information:
When using or handling 2-hydroxythiophenol, you need to pay attention to the following safety precautions:
1. 2-Hydroxythiophenol is irritating. When it comes into contact with skin, eyes or respiratory tract, rinse with plenty of water immediately and seek medical help.
2. avoid inhalation of 2-hydroxy thiophenol dust or steam, should be in a well-ventilated place of operation.
3. 2-Hydroxythiophenol is corrosive and should be kept away from fire and flammable materials.
4. During storage and use, care should be taken to avoid contact with strong acids, strong oxidants and combustibles to avoid dangerous reactions.
Please read the relevant safety manuals and chemical labels carefully before using 2-hydroxythiophenol to ensure safe use.
