Sodium fluoroacetate, also known by its trade name as a mammal poison compound 1080, is an organofluorine chemical compound with the chemical formula FCH2CO2Na. It is the sodium salt of fluoroacetic acid, and contains sodium cations Na+ and fluoroacetate anions FCH2CO−2. A colourless salt with a taste similar to table salt (sodium chloride), it is used under the name "1080" to kill small and medium mammals, including rodents. New Zealand is the world's biggest user of 1080, particularly to kill introduced brushtail possums, often with aerial spraying.
