Metüüljodiid

Metüüljodiid, also known as iodomethane, is an organoiodine compound with the chemical formula CH3I. It is a colorless liquid at room temperature with a distinct, sweet odor. Metüüljodiid is a volatile compound and is often used as a methylating agent in organic synthesis. This means it is employed to introduce a methyl group (CH3) into other molecules.

The synthesis of metüüljodiid can be achieved through various methods, including the reaction of methanol with iodine in the presence of red phosphorus, or by reacting dimethyl ether with hydrogen iodide. Its reactivity makes it a valuable reagent in laboratory settings for creating more complex organic compounds. However, it is also known for its toxicity. Metüüljodiid is a known alkylating agent, which can damage DNA and proteins, and is considered a probable human carcinogen. Due to its hazardous nature, it should be handled with extreme caution in a well-ventilated area or fume hood, wearing appropriate personal protective equipment. Its use is therefore often restricted or performed under strict safety protocols.
