Sodium trichloroacetate is primarily used as a herbicide in agricultural practices. It effectively controls a wide range of weeds, particularly in non-crop areas and for selective weed management in certain crops. Its mode of action involves disrupting plant cell metabolism, leading to the desiccation and death of unwanted vegetation. Additionally, it is employed in biochemical research as a protein precipitant, aiding in the isolation and purification of proteins from complex mixtures. In industrial settings, it serves as a chemical intermediate in the synthesis of other organic compounds, contributing to the production of various chemical products. Its applications are valued for their efficiency and versatility in both agricultural and scientific fields.
