Methyl hexanoate is the fatty acid methyl ester of hexanoic acid (caproic acid), a colourless liquid organic compound with the chemical formula CH₃−(CH₂)₄−COO−CH₃. It is found naturally in many foods and has a role as a plant metabolite. It can also be found in the cytoplasm of cells.^[1]

Methyl hexanoate is produced industrially for use as a flavouring agent.^[2]^[3] It can also be used as fragrance for a pineapple smell.^[4]

Production edit

Methyl hexanoate is produced in multi-tonne quantities for use as a flavouring agent.^[3] It is made by combining methanol with hexanoic acid.^{[citation needed]}

Uses edit

Methyl hexanoate is found naturally in foods like potatoes, tomatoes and cheese and is a constituent of some alcoholic beverages.^[2] It can be used to mimic the flavor of pineapple like its related ester ethyl hexanoate.^[4]

Safety edit

The LD₅₀ for rats is more than 5 g/kg,^[1] indicating low toxicity. When heated to decomposition, methyl hexanoate emits toxic fumes. It can cause burns.

Flammability edit

Methyl hexanoate is flammable. It has a flash point of 163 °F (73 °C).^[1]
