Opis ogólny

Trichloroacetic acid (TCA) is a chlorinated acetic acid. It is one of the major metabolite of trichloroethylene (TCE).

Zastosowanie

Trichloroacetic acid may be used for the quantification of inorganic phosphorus in various biological samples (serum, urine and stool ash solutions). It may be used for the elimination of acid-soluble and lipid phosphorous during the quantitative estimation of deoxyribonucleic acid, ribonucleic acid and phosphoproteins in animal tissues. 10% trichloroacetic acid may be employed for the preparation of radioactive proteins.
Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative in microscopy.
