Application / Uses Preparation
Methyl butanoate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odour, in this case resembling apples or pineapples. At room temperature, it is a colourless liquid with low solubility in water, upon which it floats to form an oily layer. Although it is flammable, it has a relatively low vapour pressure (40mm Hg at 30OC), so it can be safely handled at room temperature without special safety precautions.
