Sulfuryl chloride is widely used in organic synthesis as a chlorinating agent, particularly for converting alcohols, carboxylic acids, and amines into their corresponding chlorides. It is also employed in the production of pharmaceuticals, agrochemicals, and dyes, where precise chlorination is required. In the polymer industry, it serves as a cross-linking agent for modifying the properties of certain plastics and rubbers. Additionally, it is utilized in the preparation of sulfur-containing compounds and as a reagent in chemical reactions like the Friedel-Crafts acylation. Its strong reactivity makes it valuable in laboratory settings for specialized synthetic processes.
