Chloralose

Chloralose (also known as α-chloralose) is an avicide, and a 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. Either alone or in combination, such as with urethane, it is used for long-lasting, but light anesthesia.
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)
Chloralose exerts barbiturate-like actions on synaptic transmission in the brain, including potent effects at inhibitory γ-aminobutyric acid type A receptors (GABAAR). A structural isomer of chloralose, β-chloralose (also called parachloralose in older literature), is inactive as a GABAAR modulator and also as a general anesthetic.
Chloralose is often abused for its avicide properties. In the United Kingdom, protected birds of prey have been killed using the chemical.
