5-Isothiazolecarbonyl chloride, with the CAS number 3683-97-4, is a chemical compound characterized by its isothiazole ring structure, which is a five-membered heterocyclic compound containing both sulfur and nitrogen atoms. This compound features a carbonyl group (C=O) and a chlorine atom attached to the isothiazole ring, making it a reactive acyl chloride. It is typically used as an intermediate in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. The presence of the carbonyl and chlorine functionalities allows for nucleophilic substitution reactions, which are essential in forming more complex molecules. 5-Isothiazolecarbonyl chloride is generally handled with care due to its reactivity and potential to release hydrochloric acid upon hydrolysis. It is important to store this compound in a cool, dry place, away from moisture and incompatible substances. Safety precautions, including the use of personal protective equipment, are recommended when working with this compound due to its corrosive nature.
