2-ethynylphenol - Introduction
2-ethynylphenol(2-ethynylphenol) is an organic compound with the chemical formula C8H6O.
Nature:
2-ethynylphenol is a toxic white crystalline solid with a fragrant and bitter taste. It can be dissolved in non-polar solvents, such as ether and benzene, and is practically insoluble in water. It has a melting point of 66-68°C and a boiling point of 288°C.
Use:
2-ethynylphenol is widely used as a reactant and intermediate in organic synthesis. It is commonly used in the preparation of pesticides, dyes, pharmaceuticals and other organic compounds. For example, it can be used to synthesize alkynyl-containing compounds such as heterocyclic compounds and polycyclic aromatic hydrocarbons. In addition, 2-ethynylphenol can also be used as a ligand for metal ions and transition metal complexes.
Preparation Method:
There are many methods for preparing 2-ethynylphenol. One commonly used method is to react 1-bromo-2-ethynylbenzene (1-bromo-2-ethynylbenzene) with alkali (such as sodium hydroxide) in alcohol solution to obtain 2-ethynylphenol.
Safety Information:
2-ethynylphenol is a toxic compound that is irritating and carcinogenic. Wear appropriate protective equipment such as gloves, goggles and protective clothing during handling and use. Avoid inhalation, ingestion or skin contact. In case of inadvertent exposure, clean the affected area immediately and seek medical help. Do not mix it with strong oxidants to avoid dangerous reactions. Follow safe operating procedures and store and handle the compound properly.
