CH2CICH2I

1,3-Diiodopropane is an organoiodine compound with the chemical formula CH2ICH2CH2I. It is a halogenated alkane where two iodine atoms are bonded to the terminal carbon atoms of a propane chain. This compound is a colorless to pale yellow liquid at room temperature. It is soluble in many organic solvents but has limited solubility in water. 1,3-Diiodopropane can be synthesized through various methods, often involving the reaction of 1,3-propanediol with iodine-containing reagents. It is a reactive compound due to the presence of the carbon-iodine bonds. These bonds are relatively weak, making 1,3-diiodopropane susceptible to nucleophilic substitution reactions. It can act as a precursor in organic synthesis for the formation of cyclic compounds or other functionalized molecules. For example, it can be used to create cyclopropane rings through intramolecular cyclization. Safety precautions should be observed when handling 1,3-diiodopropane as it may cause irritation to the skin and eyes, and its vapors should be avoided. It is typically stored in a cool, dry, and well-ventilated area away from incompatible materials.
