Sodium trichloracetate

           

The data shown refer to sodium trichloroacetic acid. 
In many countries, the term TCA refers 
to the free acid (now accepted by ISO): this 
is a solid with an oral LD50 of 400 mg/kg 
and if used as a pesticide is placed in Class II. 
It is highly corrosive to skin
