Used primarily in organic synthesis, it serves as a key reagent for introducing trichloroacetyl groups into molecules. It is widely employed in the production of pharmaceuticals, particularly in the synthesis of active pharmaceutical ingredients (APIs) where precise chemical modifications are required. Additionally, it finds application in the manufacture of agrochemicals, aiding in the development of pesticides and herbicides. In the field of biochemistry, it is utilized for protein and nucleic acid precipitation and analysis. It also acts as a catalyst or intermediate in various chemical reactions, including esterification and acylation processes. Its strong reactivity makes it valuable in research and industrial settings for creating complex organic compounds.
