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.[1] Either alone or in combination, such as with urethane, it is used for long-lasting, but light anesthesia.[2]

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 (GABAA) receptors.[3][4] A structural isomer of chloralose, β-chloralose (also called parachloralose in older literature), is inactive as a GABAA modulator and also as a general anesthetic.[5]

Chloralose is often abused for its avicide properties. In the United Kingdom, protected birds of prey have been killed using the chemical.[6]
