Benzoic acid methyl ester ( methyl benzoate, niobe oil ) is a chemical compound , a colorless liquid with a characteristic odor, which is formed as an ester from aromatic benzoic acid when it reacts with methanol . It is a fragrance and flavoring substance that is used in the manufacture of cosmetics and in food.

use

Due to its property as a low-boiling substance, methyl benzoate is also used as a measuring fluid for heat cost allocators based on the evaporation principle. Another use is as an intermediate (in addition to methyl benzoate, for example xylene ) in the production of histological preparations.
