Boron trichloride (boron (III) chloride) is a binary inorganic compound of boron and chlorine. It is a colorless gas with pungent unpleasant odor, reacts with water. It is poisonous.
In the laboratory, boron trichloride is obtained by the decomposition of its adducts, for example, BCl3S(CH3)2, which are convenient to work with because they are solids.

- Heavy
- Colorless gas with a sharp unpleasant odor
- Fumes in damp air
Boron trichloride is a raw material for producing pure boron. It is also used in the processing of aluminum, magnesium, zinc, and copper alloys to remove nitrides, carbides, and oxides from molten metal.
Boron trichloride was used as a flux for soldering aluminum, iron, zinc, tungsten, and copper-nickel alloys. Processing liquid aluminum with boron trichloride vapors improves casting quality.
Used in the manufacture of electrical resistors for attaching carbon film to ceramic substrates. Used in plasma etching in microelectronics manufacturing. Used as a reagent in organic synthesis.
