2,2,2-Trifluoroethanesulfonyl chloride

Description:
2,2,2-Trifluoroethanesulfonyl chloride, with the CAS number 1648-99-3, is a chemical compound characterized by its sulfonyl chloride functional group and the presence of trifluoromethyl groups. This compound is typically a colorless to pale yellow liquid that is highly reactive, particularly with water and alcohols, leading to the release of hydrogen chloride gas. It is known for its strong electrophilic nature, making it useful in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. The trifluoromethyl groups contribute to its unique properties, including increased lipophilicity and stability against hydrolysis compared to other sulfonyl chlorides. Due to its reactivity, it must be handled with care, as it can cause severe burns upon contact with skin and is harmful if inhaled or ingested. In terms of applications, it is utilized in the pharmaceutical industry and in the synthesis of various fluorinated compounds, highlighting its significance in modern organic chemistry.
