Sulfur dichloride (SCl₂) is an inorganic compound, usually in the form of a reddish-brown liquid, soluble in hexane, carbon tetrachloride, and benzene. Sulfur dichloride has a melting point of about -78 °C, a boiling point of about 60 °C (decomposition), and a density of 1.355 g/cm³. 

This compound emits smoke in the air, has a pungent chlorine odor, and reacts with water to produce substances such as H2S2O3, H2SnO6 and H2SO4, and the whole process releases a lot of heat.

Sulfur dichloride is a versatile inorganic compound with various uses shown as below:

1. Organic synthesis of chlorinating agents: In organic chemistry, sulfur dichloride is often used as a chlorinating agent to make chlorides of anhydrides or organic acids.

2. Additives for high-pressure lubricants and cutting oils: In industrial applications, sulfur dichloride is used as an additive for high-pressure lubricants and cutting oils to improve their performance.

3. Industrial processing of oils and fats: In oil processing, sulfur dichloride is used to treat vegetable oils, such as corn oil, cottonseed oil, soybean oil, etc.

4. Disinfectant and biocide: It can also be used as a disinfectant and biocide for certain hygiene and medical applications.

5. Preparation of carbamate insecticides: Sulfur dichloride is an intermediate in the preparation of certain carbamate insecticides, such as carbofuran butathione and carbofuran prothion.
