2-Methyl-2-butanol (also known as tert-amyl alcohol or 2M2B) is a tertiary alcohol substance that produces depressant, hypnotic, and anxiolytic effects. Historically, it has been used in anesthesia as a component of avertin fluid mixed with tribromoethanol and water. It has a strong solvent smell reminiscent of gasoline and camphor, but with little flavor aside from a burning sensation. 2M2B's simple structure and intoxicating effects have led to its use as a recreational drug.
