Methyl benzoate is an organic compound. It is an ester with the chemical formula C6H5CO2CH3. It is a colorless liquid that is poorly soluble in water, but miscible with organic solvents. Methyl benzoate has a pleasant smell, strongly reminiscent of the fruit of the feijoa tree, and it is used in perfumery. It also finds use as a solvent and as a pesticide used đồ sộ attract insects such as orchid bees.

Synthesis and reactions[edit]

Methyl benzoate is formed by the condensation of methanol and benzoic acid, in presence of a strong acid.[1][2]

Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid đồ sộ give methyl 3-nitrobenzoate. Nucleophiles attack the carbonyl center, illustrated by hydrolysis with addition of aqueous NaOH đồ sộ give methanol and sodium benzoate.


Methyl benzoate can be isolated from the freshwater fern Salvinia molesta.[3] It is one of many compounds that is attractive đồ sộ males of various species of orchid bees, which apparently gather the chemical đồ sộ synthesize pheromones; it is commonly used as bait đồ sộ attract and collect these bees for study.[4]

Cocaine hydrochloride hydrolyzes in moist air đồ sộ give methyl benzoate;[5] drug-sniffing dogs are thus trained đồ sộ detect the smell of methyl benzoate.[6]
