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