2-Thiophenesulfonyl chloride

Description:

2-Thiophenesulfonyl chloride, with the CAS number 16629-19-9, is an organic compound characterized by the presence of a thiophene ring substituted with a sulfonyl chloride group. This compound typically appears as a colorless to pale yellow liquid and is known for its strong reactivity due to the sulfonyl chloride functional group, which can readily participate in nucleophilic substitution reactions. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water. The compound is often used as a reagent in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Due to its reactive nature, it must be handled with care, as it can be corrosive and may cause irritation to the skin and eyes. Proper safety precautions, including the use of personal protective equipment, are essential when working with this substance in a laboratory setting.
