Ethyl oxy chloride, also referred to as ethyl hypochlorite or chloroethanol, is a colorless liquid with a strong odor, denoted by the formula C2H5OCl. It serves primarily as an intermediate in organic synthesis, finding wide application in the production of pharmaceuticals and agrochemicals. Ethyl oxy chloride is valued for its ability to react with nucleophiles, enabling the introduction of the ethoxy group into organic molecules. However, due to its reactive nature and potential hazards such as respiratory irritation and skin and eye corrosion it requires careful handling under controlled conditions.
