Metüüliiodiid

Metüüliiodiid is an organoiodine compound with the chemical formula CH3I. It is a colorless liquid at room temperature and pressure. It is a volatile compound with a sweet odor. Metüüliiodiid is soluble in organic solvents but has low solubility in water. It is a relatively reactive compound due to the polarized carbon-iodine bond, making the methyl group susceptible to nucleophilic attack.

This reactivity makes metüüliiodiid a useful reagent in organic synthesis. It is commonly employed as a methylating agent, meaning it can introduce a methyl group (-CH3) into other molecules. This process, known as methylation, is a fundamental transformation in organic chemistry and is used to synthesize a wide variety of compounds, including pharmaceuticals, fragrances, and polymers. For example, it can be used to alkylate amines, alcohols, and thiols.

Metüüliiodiid is also used in the production of other chemicals. Industrially, it can be synthesized by reacting methanol with iodine in the presence of red phosphorus, or by reacting dimethyl sulfate with potassium iodide. Due to its toxicity and potential environmental impact, its handling and disposal require careful consideration. It is classified as a hazardous substance and should be used with appropriate safety precautions, including good ventilation and personal protective equipment.
