4-Chloro-1-butanesulfonyl chloride

Description:
4-Chloro-1-butanesulfonyl chloride, with the CAS number 1633-84-7, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a butane chain. This compound typically appears as a colorless to pale yellow liquid and is known for its strong reactivity, particularly with nucleophiles due to the electrophilic nature of the sulfonyl chloride group. It is soluble in organic solvents such as dichloromethane and ether but is generally insoluble in water. The compound is often used in organic synthesis as a reagent for the introduction of sulfonyl groups into various substrates, facilitating the formation of sulfonamides and other derivatives. Due to its reactive nature, it must be handled with care, as it can release toxic gases upon contact with moisture or water. Safety precautions, including the use of personal protective equipment and proper ventilation, are essential when working with this substance.
