2-Metil-2-butanol (terc-amil alkohol, 2M2B, amilen hidrat) je jedan od izomera amil alkohola. On je čista, bezbojna tečnost sa jakim mirisom peperminta ili kamfora.[7][8] Kod ljudi on ispoljava sedativno, hipnotičko, i antikonvulsivno dejstvo slično etanolu pri gutanju ili udisanju. Ranije je korišten u medicini za te svrhe.[9] On je aktivan u dozama u opsegu od 2.000-4.000 mg, te je 20 puta potentniji od etanol.a[10][11] Njegov hipnotički potencijal je između hloral hidrata i paraldehida.[12] In humans, 2-methyl-2-butanol is metabolized primarily via gluconoridation and oxidation to 2,3-dihydroxy-2-methylbutane.[13] Prekomerna doza proizvodi simptome slične alkoholnom trovanju.
