Bromodichloroacetonitrile ([(dichlorobromomethyl)cyanide]) is a synthetic chemical compound characterized by a strong, pungent odor. It appears as a yellowish, oily, semi-transparent liquid, easily decomposing in water to produce harmful and irritating gases. The compound reacts similarly when in contact with moist air, yielding vapors that may cause damage to the eyes, respiratory tract, and skin.
