Other names :
2-Heptanone ; Amyl methyl ketone ; Butyl acetone ; Eastapure MAK ; Heptan-2-one ; Ketone C-7 ; MAK ; Methyl pentyl ketone ; Pentyl methyl ketone
Volatility :
Head
Uses in perfumery :
Methyl Amyl Ketone is used in fruity notes, lavender notes (in trace amounts to give power from the top) and spicy notes.
Natural availability :
Methyl Amyl Ketone is present in many plants and cheeses. The plant that contains the most is a green alga called Ulva Rigida. However, it is the synthetic Methyl Amyl Ketone which is most often used in perfumery.
Year of discovery :
Data not available.
Other comments :
Comparing it with Methyl Hexyl Ketone, the latter has a more earthy than mushroom smell, as does Methyl Amyl Ketone.

Synthesis route :
Methyl Amyl Ketone is synthesized by a catalytic oxidation of 2-heptenol. This oxidation can be done in the presence of sodium hypochlorite at a high temperature, for example.
Synthesis precursor :
A hydrogenation of Methyl Amyl Ketone converts it to 2-heptanol, which also has an olfactory interest.
Isomerism :
When the ketone function of Methyl Amyl Ketone is relocated, the smell can radically change. For example, Ethyl Butyl Ketone has a greener, oily and fruity smell. Aldehyde C-7 is a constitutional isomer of Methyl Amyl Ketone, but has a totally different smell from the latter.
