CH3CHI2

CH3CHI2, more commonly known as iodoethane or ethyl iodide, is a halogenated hydrocarbon with the chemical formula C2H5I. It is a colorless liquid at room temperature and pressure, possessing a distinctive, sweet odor. Iodoethane is a volatile compound and is soluble in most organic solvents but has limited solubility in water.

Industrially, iodoethane can be synthesized through various methods, including the reaction of ethanol with iodine in the presence of red phosphorus, or by reacting ethane with iodine under specific conditions. It is primarily used as an alkylating agent in organic synthesis. This means it is employed to introduce an ethyl group (CH3CH2-) into other organic molecules. This process is crucial in the creation of various pharmaceuticals, dyes, and other fine chemicals.

Due to its reactivity, iodoethane must be handled with care. It is considered an irritant and should be stored in a cool, dry, and well-ventilated area away from sources of ignition and oxidizing agents. Its vapor can form explosive mixtures with air. While it has found applications in organic synthesis, its use is carefully managed due to its chemical properties and potential hazards.
