    Trichloroacetic acid, a colorless crystalline solid, is commonly utilized in liquid solutions. It has the ability to absorb moisture from the surrounding air and become syrupy. 

Uses：

1. Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative, as a laboratory reagent, a herbicide, in medicine, and in microscopy.

2. Trichloroacetate (TCA) is used primarily for the selective control of annual and perennial grass weeds in cropland and noncropland.  

3. As a reagent for albumin detection;  in making herbicides.  It is found as a by-product after chlorination of water containing humic materials.
4. Protein precipitation reagentTrichloroacetic acid is used as a precipitating agent in biochemistry for precipitation of proteins, DNA and RNA.  It is an active ingredient used in cosmetic treatments like chemical peels, tattoo removal and the treatment of warts including genital warts.  It is also used to determine protein concentration and as a decalcifier and fixative in microscopy.
