Thionyl chloride is a multi-industrial colorless to pale yellow fuming liquid chemical with a sharp, suffocating odor. Thionyl chloride used in industries as a chlorinating agent in the manufacture of acyl chlorides and organosulfur compounds. SOCl₂ reacts violently with water, releasing sulfur dioxide and hydrogen chloride gases. Due to its high reactivity and volatility, Sulfinyl Chloride is essential in pharmaceuticals, agrochemical synthesis, and dye intermediates production.
