Hexachlorophene, also known as Nabac, is an organochlorine compound that was once widely used as a disinfectant. The compound occurs as a white odorless solid, although commercial samples can be off-white and possess a slightly phenolic odor. It is insoluble in water but dissolves in acetone, ethanol, diethyl ether, and chloroform. In medicine, hexachlorophene is useful as a topical anti-infective and anti-bacterial agent. It is also used in agriculture as a soil fungicide, plant bactericide, and acaricide. It has also been reported to bind tubulin, blocking its polymerization.
