| Use | for organic synthesis. Ethyl M-aminobenzoate mesylate (Tricaine[886-86-2]) is a fish anesthetic. used as intermediate in organic synthesis |
| production method | is obtained by esterification of M-aminobenzoic acid with ethanol in the presence of hydrochloric acid. Anhydrous ethanol was cooled while keeping it below 10 °c, hydrochloric acid was passed to saturation, and dried m-aminobenzoic acid was added. Then heated to reflux for 24h. After recovering the ethanol, it is poured into ice water, neutralized to pH 8 with sodium carbonate, and then washed with water to obtain a crude product. |
