What is iodine trichloride?

Iodine trichloride, also known as iodine chloride, is a chemical compound with the formula ICl3. It is a dark brown to dark red solid that is highly reactive and unstable.

Iodine trichloride is primarily used as a reagent in organic synthesis, particularly in the conversion of alcohols to alkyl chlorides. It can also be used as a chlorinating agent, oxidizing agent, and as a catalyst in certain reactions.

This compound is highly toxic and should be handled with care. It can react violently with water and release toxic fumes of hydrochloric acid and chlorine gas. It is also corrosive to metals and can cause burns upon contact with skin or eyes.

Iodine trichloride has limited commercial applications due to its hazardous nature, but it is an important compound in certain chemical reactions in the laboratory.
