Infobox references

Chlorobutanol, or trichloro-2-methyl-2-propanol, is a chemical preservative, sedative hypnotic and weak local anaesthetic similar in nature to chloral hydrate. It has antibacterial and antifungal properties. Chlorobutanol is typically used at a concentration of 0.5% where it lends long term stability to multi-ingredient formulations.

Chemical synthesis

Chlorobutanol is formed by the simple nucleophilic addition of chloroform and acetone. The reaction is base driven by potassium or sodium hydroxide.
