metüüljodiidi

Metüüljodiidi, also known as iodomethane, is an organoiodine compound with the chemical formula CH3I. It is a colorless liquid with a sweet odor, though it is volatile and its fumes are irritating. Metüüljodiidi is a polar molecule and is slightly soluble in water but miscible with many organic solvents.

Historically, metüüljodiidi has been used as a methylating agent in organic synthesis. It readily reacts with nucleophiles, transferring a methyl group. This property made it useful in the preparation of various organic compounds, including pharmaceuticals and pesticides. It was also employed as a fumigant and insecticide, though its use in these applications has largely been discontinued due to toxicity concerns.

Metüüljodiidi is a known toxin and a suspected carcinogen. Exposure can occur through inhalation, skin absorption, or ingestion. Symptoms of exposure can include headache, dizziness, nausea, and respiratory irritation. Due to its hazardous nature, handling metüüljodiidi requires appropriate safety precautions, including working in a well-ventilated area and using personal protective equipment.

In modern organic chemistry, while metüüljodiidi remains a useful reagent, safer alternatives are often preferred when possible. Its production and use are typically confined to laboratory settings or industrial processes with strict safety protocols in place.
