| Use | Ethyl 3-aminobenzoate methyl sulfonate is the most effective and widely used live fish transportation anesthetic. After MS-222 enters the fish body, it mainly accumulates in the spleen and liver, and its content in the muscles is very small. |
| In vitro study | Tricaine methanesulfonate in powder form easily can become airborne and could become hazardous to the handler. Tricaine methanesulfonate (TMS) solution is photosensitive (its color changes with light exposure), although the color change does not necessarily indicate significant activity decrease and thus color should not be used to gauge degradation. |
