| Methyl hexanoate Usage And Synthesis |
| Description | Methyl hexanoate is the methyl ester form of hexanoate with fruity type odor and flavor. It is formed by the esterification between methanol and hexanoate. It can be found in many sources such as wine grapes, melon, raspberry, blackberry, plum, quince, apple brandy, wines, Bourbon vanilla, coffee, black tea, potato, tomato, cheeses, rye bread, meats and other foodstuffs. Its major application is used as cosmetic, flavor and fragrance agents.

Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Methyl hexanoate reacts with strong oxidizing agents and strong bases. | | Fire Hazard | Methyl hexanoate is combustible. | | Flammability and Explosibility | Flammable | | Purification Methods | Pass it through alumina and distil it before use.
