Sulfuryl chloride (Cat No.: R029837) is a highly reactive, colorless liquid used as a chlorinating and sulfonating agent in organic synthesis and industrial chemistry. It decomposes upon heating to release sulfur dioxide and chlorine gases, making it effective for introducing chlorine atoms into aromatic and aliphatic compounds. Common applications include the synthesis of pesticides, dyes, pharmaceuticals, and intermediates. Due to its corrosive and toxic nature, it requires careful handling under controlled conditions, typically in fume hoods with appropriate protective equipment.
