| Common Name | Tropate |
|---|
| Description | Tropate, also known as Tropic acid or alpha-(Hydroxymethyl)phenylacetic acid, is classified as a beta hydroxy acid or a Beta hydroxy acid derivative. Beta hydroxy acids are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Tropate is considered to be soluble in water and acidic. Tropate can be synthesized from hydratropic acid and propionic acid. Tropate can be synthesized into tropan-3alpha-yl 3-hydroxy-2-phenylpropanoate |
