236739-03-0 - Introduction
1,4-difluoro-2-(methylsulphonyl)benzene is an organic compound with the chemical formula C7H6F2O2S. It is a colorless or light yellow liquid with a pungent odor.
One of the main uses of this compound is as a pesticide intermediate. It can be used to synthesize a variety of insecticides and herbicides. In addition, it can also be used as an intermediate in the pharmaceutical field for the synthesis of drugs and other biologically active molecules.
The main method for preparing 1,4-difluoro-2-(methylsulphonyl)benzene is through a fluoroalkylation reaction. First, phenylthione (benzenesulphonyl chloride) is reacted with carbon difluoride to give 1,4-difluoro-2-thioacylbenzene (1, quinone). Then, 1,4-difluoro-2-sulfoylbenzene was reacted with sodium formifide to give the final product 1,4-difluoro-2-(methylsulphonyl)benzene.
Regarding safety information, 1,4-difluoro-2-(methylsulphonyl)benzene has certain toxicity. Wear protective gloves, goggles and protective clothing during use, and ensure that the operation is carried out in a well-ventilated place. Avoid inhaling its vapors or touching the skin. For accidental contact, flush the affected area immediately with plenty of water and seek medical help. During storage, it should be kept away from fire and oxidant, stored in a closed container, and the storage temperature should be controlled below room temperature.
When using or handling this compound, it is important to follow safe operating procedures and operate in accordance with relevant regulations and standards.
