4-Chloro-2-fluorobenzenesulphonyl chloride

Description:
4-Chloro-2-fluorobenzenesulphonyl chloride, with the CAS number 141337-26-0, is an aromatic sulfonyl chloride compound characterized by the presence of a sulfonyl group (-SO2Cl) attached to a benzene ring that also bears a chlorine atom at the para position and a fluorine atom at the ortho position. This compound is typically a colorless to pale yellow solid and is known for its reactivity, particularly due to the sulfonyl chloride functional group, which can undergo nucleophilic substitution reactions. It is often used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. The presence of both chlorine and fluorine substituents can influence its chemical reactivity and physical properties, such as solubility and boiling point. As with many sulfonyl chlorides, it is important to handle this compound with care due to its potential to release toxic gases upon hydrolysis and its corrosive nature. Proper safety precautions should be taken when working with this substance in a laboratory setting.
