18494-87-6 - Introduction
It is an organic compound with the chemical formula C6H3SO2Cl. The following is a description of its nature, use, preparation and safety information:
Properties: It is a colorless to light yellow liquid that has a pungent odor at room temperature. It has a melting point of 5-7 degrees Celsius and a boiling point of 157 degrees Celsius. It is soluble in common organic solvents such as ethanol and ether, but insoluble in water.
Uses: chloride is commonly used as a reagent in organic synthesis, especially in the synthesis of olefins and aromatic compounds. It can be used to introduce sulfonyl chloride functionality, for example in the synthesis of sulfonyl chloride derivatives of benzothiophenes. In addition, it can also be used in drug synthesis, dye synthesis and other organic synthesis reactions.
Preparation method: The preparation of chloride is generally obtained by reacting benzothiophene with sulfonyl chloride. The reaction needs to be carried out in an appropriate solvent, and the reaction conditions are controlled at low temperature to avoid the occurrence of side reactions.
Safety information: chloride is an irritating compound that can irritate the eyes, skin and respiratory tract. Wear appropriate protective equipment such as gloves, face shield and goggles to ensure safety during operation. At the same time, it should be stored in a dry, cool place, away from fire and flammable substances. In the process, should avoid contact with fire or high temperature environment, in order to prevent its burning or explosion. If the compound is accidentally spilled or inhaled, wash the affected area immediately and seek medical help.
