3-Methyl-3-octanol is a chemical compound from the group of alkanols .

Occurrence

3-Methyl-3-octanol was found in extracts of the fungus Antrodia camphorata . The compound also occurs as a metabolite in the biodegradation of polyethylene and polypropylene .

Extraction and presentation

3-Methyl-3-octanol can be obtained by reacting ethylmagnesium bromide with 2-heptanone . Alternatively, methylmagnesium bromide can be reacted with 3-octanone , or n-pentylmagnesium bromide with butanone . This reaction produces a 1: 1 mixture ( racemate ) of ( R ) -3-methyl-3-octanol and ( S ) -3-methyl-3-octanol, which is also ( RS ) -3-methyl-3- is called octanol.

properties

3-methyl-3-octanol is a colorless liquid.
