Used primarily as an intermediate in organic synthesis, it plays a key role in the production of pharmaceuticals, agrochemicals, and other specialty chemicals. It is particularly valuable in the synthesis of herbicides, such as those in the chloroacetamide class, which are widely used in agriculture for weed control. Additionally, it serves as a reagent in the modification of peptides and proteins, aiding in the development of bioactive compounds. Its reactivity with various organic compounds makes it a versatile tool in chemical research and industrial applications. Proper handling is essential due to its corrosive and toxic nature.
