Ethyl fluoroacetate is primarily used in organic synthesis as a fluorinating agent and building block for fluorinated compounds. Researchers employ it in the development of pharmaceuticals, agrochemicals, and specialty materials due to its ability to introduce fluorine atoms into target molecules. It is also utilized in biochemical studies to investigate enzyme inhibition and metabolic pathways. Strict safety measures must be followed due to its high toxicity.
