CAS 721-64-2

4-(Trifluoromethyl)benzeneethanesulfonyl chloride

Description:

4-(Trifluoromethyl)benzeneethanesulfonyl chloride, with the CAS number 721-64-2, is an organic compound characterized by the presence of a sulfonyl chloride functional group attached to a benzene ring that also features a trifluoromethyl substituent. This compound typically appears as a colorless to pale yellow liquid or solid, depending on the temperature and purity. It is known for its reactivity, particularly due to the sulfonyl chloride group, which can undergo nucleophilic substitution reactions, making it useful in organic synthesis for introducing sulfonyl groups into various substrates. The trifluoromethyl group enhances the compound's lipophilicity and can influence its electronic properties, making it a valuable building block in pharmaceuticals and agrochemicals. Additionally, it is important to handle this compound with care, as sulfonyl chlorides can be corrosive and may release toxic gases upon hydrolysis. Proper safety precautions, including the use of personal protective equipment and working in a fume hood, are essential when working with this substance.
