Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid with a fruity odor resembling apples or pineapples. It is present in small amounts in several plant products, most noticeably pineapple oil. At room temperature, it is a colourless liquid with a low solubility in water, upon which it floats to form an oily layer.
It can be produced by distillation from essential oils of vegetable origin, but is also manufactured on a small scale for use in perfumes[2] and as a food flavouring, as well as being a component of biodiesel.[3]
