Chloralose is an avicide, rodenticide used to kill mice in temperatures below 15 °C. It is also widely used in neuroscience and veterinary medicine as an anesthetic and sedative.[1]

Chemically, it is a chlorinated acetal derivative of glucose.

It is listed in Annex I of Directive 67/548/EEC with the classification Harmful (Xn)
