China and the United States are the leading exporters of thionyl chloride, accounting for the largest shares of global supply, while India, South Korea, and Germany represent the top importing countries. Thionyl chloride prices have remained relatively stable amid steady cross-border flows, with minor regional fluctuations tied to pharmaceutical and battery material demand. Imports by India and South Korea have grown steadily since 2022, reflecting expanding domestic production of active pharmaceutical ingredients and lithium-based batteries.
Thionyl chloride is a colorless to pale yellow, fuming liquid with a pungent, suffocating odor and high volatility; it has a boiling point of 76 °C and a melting point of −105 °C. It is an inorganic chlorinating agent and acid chloride derivative, widely employed as a reactive intermediate in organic synthesis. Its primary industrial use is for the conversion of carboxylic acids and alcohols to acyl chlorides and alkyl chlorides, respectively—key steps in the production of active pharmaceutical ingredients, agrochemicals, and specialty chemicals. It is extensively applied in the synthesis of herbicides, insecticides, and drug candidates, particularly in processes requiring mild, non-oxidizing chlorination conditions.
For making acyl chlorides, to replace hydroxide of sulfhydryl groups with chlorine atoms.
It is colorless or light yellow volatile liquid with a strong suffocating odor. It can also be miscible with benzene, chloroform and carbon tetrachloride.
